Title: T-2011 – what’s behind the number?
Post by: Schruiber on February 13, 2011, 02:01:55 PM: After introducing myself earlier today I am very much honored to introduce our new educational project to the LSR community:

The Granite Falls High School “LSR-UC” car is going to become a “rolling educational STEM laboratory” run by a mixed team of girls and boys grade 9-12. This will raise the bar and apply Science, Technology, Engineering and Math in a real world problem solving setting. After the April Shell Eco-marathon fuel efficiency race in Houston, TX our 2011 Diesel Urban Concept Car will be modified for use of B20 Bio Diesel.

We plan to test this car with a comprehensive protocol first at Sea Level in 50 degrees Fahrenheit using the PACCAR Technical Test Center in Mt. Vernon, Washington and then second, repeat the same test protocol at 4,500 feet altitude at 90 degrees Fahrenheit at World of Speed in Bonneville, Utah. There, under the watchful eye of the technical inspectors we will use part of the 3 mile short course unique to the WOS for a variety of scientific testing September 14-17, 2011. It offers a unique setting with options to individualize and tailor performance protocols. Visiting schools can participate in the learning with hands-on activities.

We will attempt to get on the books as a first ever youth school team to raise awareness for alternative fuels, and make it an educational outreach endeavor across State lines. T-2011 is the temporary race number our car will carry!

Our Major Sponsors and Supporters are:

PACCAR Technical Test Center, Mt. Vernon, WA - use of test track and provider of B20 biodiesel
Center of Excellence in Aerospace and Advanced Materials Manufacturing, Everett, WA - Sponsorship to fund advanced carbon fiber materials on our car and raise awareness for alternative fuels.
Target550 – Treit and Davenport LSR – Technical and Logistics/PR Consulting for testing at Bonneville, UT
BECU (Boeing Employee Credit Union) – School Grant to fund test and data collection software and technology.

Post by: Milwaukee Midget on February 14, 2011, 07:58:46 PM: I applaud this project, and wish the team success!

One of the most rewarding things that happened at WOS last year was when busloads of High School students from Salt Lake City showed up. They walked the pits, asked great questions, and were very interested in what was happening.

That you've taken this to the next level, and that the USFRA has welcomed you to this event is great news.

Your team stands in excellent company with those who have tested their vehicles on the salt - Ford, Rolls Royce, MG, Chrysler, along with numerous university endeavors. That a High School program is working in this field with experimental and cutting edge technology lets me know that the future is bright.

I will be at the World of Speed event, and I look forward to seeing this vehicle and meeting the team members.

Sincerely,

Chris Conrad

Post by: charlie101 on February 17, 2011, 12:17:41 PM: Really looking forward to follow your team build! If your team half as good as Freud to fill us in whats happening it will be a 'treit' to follow! I really hope the team will be able to share extensivly the engine tech at that experimental level, what conclutions and desicions your team makes, computer software and simulating programs youre using, what you do to to the engine to utilize maximum energy out of the petrol, new materials, friction reduction and all that. The cage or aero can never compete with anything what Marlo is building, thus slightly less interesting in my opinion, but your engine tech can be at the forefront as good as the best! I would love to see you make this your teams discussion board!
Title: Re: T-2011 – what’s behind the number?
Post by: Woodstock on February 17, 2011, 05:02:05 PM: Schruiber, you should talk to the people at PACCAR Tech Center to see if they could hook you up with the University of Washingtons' low speed wind tunnel they had on campus that we used at Kenworth 30 plus years ago (if it's still there). Boeing aslo has one. Low speed I don't know. It will be interesting to follow your project on this website... keep us posted.

Title: Re: T-2011 – what’s behind the number?
Post by: Moxnix on February 17, 2011, 10:47:21 PM: Hoi Schruiber. As your school is a public school, and the U.ofW. is a state university, you might contact the Kirsten Wind Tunnel team and ask about costs and scheduling. Then perhaps a reasonable grant request from a foundation may be available.
Title: Re: T-2011 – what’s behind the number?
Post by: Schruiber on February 22, 2011, 12:12:58 AM: Thank you for your postings re. data and aero. I have been working on figuring out data acquisition systems within our budget to go with our intended iPhone/iPad dash board idea and use of computer for downloaded data analysis; I will soon post a question for input, suggestions and recommendations. For aero testing, the UW tunnel is something I heard of and shall inquire as you suggest. At the PACCAR test track and Bonneville we want to tuff the car and video. In 2009 we built a almost 10 feet long low speed wind tunnel drawing about 35mph with a large house fan; we can test 1:10 scale models in the 1x1 foot cross section which is 2 feet long. At current it is mechanical using a scale from our science department, yet we have purchased electronic sensors to upgrade so we can test drag and lift, then download for analysis. We are also adding a flow straightener on the intake side. Attached picture is from our annual Middle School - High School mini eco car camp outreach, where our HS girls teach the MS girls about design, aero and how to make models from foam, then test - needless to say it's a fun 2 days, including food, facepaint and music!

Post by: Schruiber on February 22, 2011, 04:55:31 PM: I am gong to post a few pictures these next couple of days of how it all began - with research and "home work" at World of Speed 2008 for building models to getting launched with the Shell Eco-marathon - first with the ShopGirls then with UrbanAutos - and now onto coming full circle of bringing the Urban car to run on biodiesel at WOS 2011. At the beginning of the 08 school year I got a new freshmen class for career advising, yet being during WOS I had to do it with a Youtube video http://www.youtube.com/watch?v=ScLe86E-uv0 from the salt - where, not really knowing much I boldly announced that we were going to build a car!

Title: Re: T-2011 – what’s behind the number?
Post by: Milwaukee Midget on February 22, 2011, 05:30:10 PM: School bus yellow would be a great color - it worked for George Follmer in the old Trans Am Mustang in the early 1970's, and would make for a great statement regarding who's putting this thing together.
Title: Re: T-2011 – what’s behind the number?
Post by: Schruiber on February 23, 2011, 09:05:44 AM: Schoolbus Yellow might just go very well with our black "do not paint - major cool factor" carbon fiber doors; add a white roof and ......do not add a stop sign - because we want to go, and a one sided "airbrake" might just ruin the run at the end !

See our short stop-motion carbon fiber panel video, made by Matt Weaver of Fiberglass Supply; he is one of our sponsors and works with the students as mentor.

Title: Re: T-2011 – what’s behind the number?
Post by: Schruiber on February 27, 2011, 02:38:34 PM: This week we had 2 snow days = no school, no work, so some of us made up by coming in Saturday. Lots of work remains to get this car ready for Houston in mid April. I’ll have 3 different posts.

Photo 1 - Our front suspension is being made by “re-purposing” a front fork from a 1975 250 Honda Elsinor and other bits and pieces. Tim designed the parts using a Morgan set-up as inspiration. He then works with one of our volunteers and sponsors, Ed Staheli at his machine shop to get the parts made and learning machining at the same time.
Photo 2 - Drive train this year is a Comet Vario drive combined with #35 chain and a large, yet to be manufactured free wheel. Last year we used a Nu-Vinci variable speed drive until it fried then just plain centrifugal clutch and chain drive with a fixed ratio. Engine is a clone Yanmar 4.5hp 210cc direct injection diesel.
Photo 3 – the team wants “cool looking” new LED head dual head lights flush fitted into the nose. To meet the regulations and start building the brackets we made a mock-up using parts from last years’ nose building jig to get the curvature and location right, using the pink foam mock-wheel to check for clearance
Photo 4 – Aron and James, both seniors and the drivers of the car fitting the ¾” balsa core carbon fiber floor which will become the integrated floor – tub – seat; It’s a hybrid set-up as we retain the lower and upper steel tube longerons.
Title: Re: T-2011 – what’s behind the number?
Post by: Schruiber on February 27, 2011, 02:40:31 PM: Photo 1 -4 – one of the requirements for the car is to carry a suit case 20x40x50 cm. For their first ever sheet metal work, freshmen Brooke and Jasmine are making one from very thin aluminum flashing and some angle pieces. Layout, mock-up, shearing, cutting, bending, flanging, dimpling, and riveting (both solid and pop rivets) are all new experiences involving lots of math applied. The suitcase will have just a small opening on one end to insert the 12 lbs steel plate to bring-up the minimum weight of the drivers to the required 150 lbs. It all will lock safely into place in the car.
Title: Re: T-2011 – what’s behind the number?
Post by: Schruiber on February 27, 2011, 02:42:15 PM: Photo 1+2 – A good number of ideas and solutions are shared between the ShopGirls’ high mileage prototype car and UrbanAutos. Shante,their team manager being tired of connecting and disconnecting the electrical plug every time the rear body needs removal (and that is often) created the “contact” plate and laminated copper strips into the fiberglass body for the required starter light.
Title: Re: T-2011 – what’s behind the number?
Post by: Schruiber on March 13, 2011, 10:17:49 PM: we had a good and busy week - major accomplishments were the front suspension and steering. The front suspension is a "Morgan" style upright, made from the front fork of a 1975 Honda Elsinor - we call it "re-purposing"; it's good basic machining which our students do at one of our volunteers tool and die machine shop.

Of course being Swiss we applied the "Swiss Cheese" drill holes to lighten the pieces.

The rack and pinion was installed in the center of the car, yet we are using only one side in order to have equal length steering rods (off center and center of the driver there was no room to add a steering rod to the left side. The steering set-up will also incorporate the positive steering stop required. for the educational math there was camber and castor as well as Ackerman steering angle

In the right side of the last picture you see the required 20x40 x50 cm piece of luggage (your max. overhead carry-on dimension piece). Jasmine and Brooke made it from thin alu flashing; it weighs only 2.5 lbs which is good as the piece is part of the car empty weight (those are the rules). It will eventually carry the additional weight required (steel plates) to bring the driver up to the minimum weight.

Work this coming week will be the carbon fiber tub and seatbelt attachments + new LED "super cool" and very bright dual headlights - stay tuned

Post by: Schruiber on April 07, 2011, 10:44:59 PM: And here a "life signal" again - thank you for your nice comments and for keeping up with what we do. Yesterday, we finally finished the Urban car and on the short test runs got it to do what we wanted it - after we reinstalled the idle governor control :-D. Attached pictures show the finished car and cockpit. The rules require it to carry a overhead size luggage piece; we carry it in the passenger side and run it a single seater. A seat filler piece and additional 5-point harness will convert it quickly to a 2-seater. The doors and cockpit tub are made from balsa or foam core carbon fiber 3/8-3/4" thickness. For the "fun factor" we have LED light strips in the head light buckets and underglow under car with a 31 different mode controller ! More detail photos to follow - stay tuned

Once again we were the only 2-seat car, so - Satuday evening our senior student/driver James Vest gave my 90 year old mother-in-law Tess Taylor a ride in the parade lap - needless to say Mom had a blast. The ShopGirls placed second in the protoype diesel category with 378 MPG and won the Safety Award.

Post by: Seldom Seen Slim on April 18, 2011, 12:13:21 PM: Wonderful news -- and great effort on the part of all of you -- students and instructors alike. What a great way to get youngsters (?!) started in life.

I went to college at Michigan Tech, and when I was there the school had a girl/boy ratio of 1:19. Then Tech started running programs for girls and women - Women In Engineering was just one of 'em. Now the school has about 3 or so men per woman - and there are many more women in what we used to call the "guys" fields of study, like engineering and physics and so on.

This is a great start, I say again, to what could be a big help for our whole country to get more technically-trained folks in the workplace. Corngratulations.

I don't know, Freud - those are some pretty rare parts they've put in that vehicle.

Gosh - I just thought. The Urban Concept is a two seater. If they put together 499 more of them, switch it over to gas, and bore it out to 1000 cc's, they could run I/GT :-o

Maybe I should stop encouraging them . . . :-D

All kidding aside, there's a saying in this sport . . .

Post by: Schruiber on June 12, 2011, 12:30:24 PM: It's been a while since my last post about our "LSR Urban Concept Car" (if LSR and Urban Concept go together?) - here an update. Yesterday we spent the day at the PACCAR Test Center in Mt. Vernon (see an aerial view at http://www.paccar.com/company/PTC_open_house.asp ) After switching back to the higher speed rated Pirelli Diabolo 100/80-16 tires (from the Michelin low resistance tires we used in Houston) we ran 2 tests

- First a 6 miles fuel efficiency, that's 4 laps on the banked oval, using pump mineral diesel then repeat the same session with B20 biodiesel; best result overall with the B20 was 159ml/6miles = ~142 MPG.

- Second we did the 2/10 mile acceleration test which we will repeat at World of Speed running a best of 28:92 seconds, again with the B20 (and we removed the muffler :-D ) now with some lengthy math, since all Elapsed Time calculators only give me the 1/4 mile, I got 24.896 mph. Can someone please verify or help with a formula. I will have the students figure it out tomorrow too.

Additionally we tuffed the current car body to get some aero flow feedback. We did not finish the longtail LSR body in time to test. Stay tuned for the 35mph photo on the banked oval (no at that speed it is not self steering)

all in all a great day for 5 students and us adults - glad one of them had the 24 Le Mans live on his mobile phone !

Picture 1 - we added a few tuffs (fuzzies) with blue tape - nothing is going on in the center of the nose - front fender - side of the roof and back-top of body show more flow and rough air.
Picture 2 - at about 33+ mph at the top of the bank - how much fun can a kid have (and still be within the liability insurance guidelines of a school district?)
Picture 3 - So, you want to drive one of these Urban cars on the road......?
Picture 4 - Testing cars is serious business; team photo at the end of a fun and educational day.

Post by: Schruiber on June 15, 2011, 11:31:25 AM: And here a first glimpse at our LSR tail body mock-up/jig. It will curve to a point and will be made from styrofoam and fiberglass. We will be able to split this rear body at the max. car length allowed by the Shell rules (350cm), having some sort of a Kamm effect blunt tail, or use the whole tear drop shaped tail, which brings the overall car lenght to 430cm (~14 feet). The idea is to have many ways to test all sorts of things and make it educational; Philippe the Firewall our mascot is all smiles (and he is not a ginger bread man)

Post by: Schruiber on July 14, 2011, 01:53:00 PM: Quiet time at school - kids are off on vacation. Nonetheless a lot of logistics and preparation needs to get done, including drafting a "fitting the occasion" new LSR-Long Tail logo for our T-shirts, vests, perhaps even a sticker etc. There is room for sponsor logos :-D

I also contacted the -Save the Salt - Coalition to find out if they would be interested in us carrying their message/web address on the new tail as our contribution to raise awareness.

What else? It's still raining here in WA State !

Post by: Schruiber on July 19, 2011, 11:10:03 PM: Thank you Marlo and Freud for your offer. I understand it's a long trailer - so - we thought we make a really long tail to fill the trailer and fit the occasion :)

A good few hours of work at school today to continue the LSR long tail build

Picture 1 Jasmine and Tim using our homebuilt hotwire and templates to cut the 1/2" foam for the top. Bandsaw and table saw were used to cut the other pieces.
Picture 2 The l-o-n-g tail; we marked the original urban car tail in red; then there will be an intermediate "Kamm" tail and the tear drop LSR tail bringing the base 9'8" long car to 14'5". 5.6 oz Fiberglass with epoxy resin in-and outside is next.

.........and then there is the $$$green$$$ - your (sponsor) logo here message :-)

picture 2 - The bulkhead is "re-purposed" from a just right size Shell poster foam core board we picked-up at the last Shell Eco-marathon in Houston. This saved us time!

Additional News - Advanced Refining Concepts http://www.clearrefining.com/ sent us 10 gallons of their GDiesel to use for our alternative fuel testing at World of Speed. It was alternative fuel coordinator Kent Singleton who made us aware of this new fuel.

Geoffrey Green (American Jaguar elsewhere on this forum) already donated a Lexan NACA air inlet, after I saw your set-up.
Target 550, Marlo Treit, his crew and Freud are transporting our car to Bonneville and will lend support on the salt.

The biggest expense for the kids and us is most often travel, lodging and food (teenagers eat a lot),........and that rocket motor we want to install :-D

In return sponsors willt their name and/or logo will be added to our car and our website http://live.gfalls.wednet.edu/ecoteams/sponsors/ additional each one will get a team photo and be added to the newsletter list.
See below for more info about our WOS venue
Thank you in advance for all your help - we look forward meeting you all on the salt in T-18 Days ! (= lots of overtime 'til then)

T2011 – What’s behind the number?
August 24, 2011 – for immediate release
Granite Falls High School UrbanAutos team won 1st place at this years’ Shell Eco-marathon® in Houston, Texas. Additionally, they now hold the new Americas Record for the Urban Concept Diesel Category with 186 MPG.
For our next tests the car will use GDiesel® and B20 Biodiesel and is going to become a “rolling Career and Technical Education (CTE) - STEM laboratory” run by a mixed team of girls and boys grade 9-12. This Project Based Learning will raise the bar and apply Science, Technology, Engineering and Math in a real world problem solving setting.
We will attempt to get on the books as a first ever youth school team to raise awareness for alternative fuels, and make it an educational outreach endeavor across State lines. Visiting schools (Morningside Elementary, Salt Lake City) are participating in the learning with hands-on activities. Multi-Age classes in Granite Falls are linked in via SKYPE and YouTube.
First, in early June we tested this car with a comprehensive protocol at Sea Level in 60-70 degrees Fahrenheit using the oval track at PACCAR Technical Center in Mt. Vernon, Washington for fuel efficiency and acceleration over 2/10 mile.
Second, we will repeat the same test protocol at 4,300 feet altitude at ~ 90 degrees Fahrenheit at World of Speed in Bonneville, Utah. There, under the watchful eye of the technical inspectors we will use part of the 1 mile short course unique to the WOS for a variety of scientific testing September 14-17, 2011. It offers a variety of options to individualize and tailor performance protocols. T2011 is the temporary race number our car will carry!
Our Major Sponsors and Supporters to datefor this venue are:
•   PACCAR Technical Center, Mt. Vernon, WA - use of test track and provider of B20 Biodiesel
•   Center of Excellence in Aerospace and Advanced Materials Manufacturing, Everett, WA - Funding for outreach to
raise awareness for alternative fuels and advanced composite materials in an educational setting.
•   Target550 /Treit and Davenport LSR, Aurora, OR – Technical and Logistics/PR Consulting for testing at Bonneville, UT
•   ARC - Advanced Refining Concepts, LLC, Sparks, NV – GDiesel® Sponsor
•   USFRA – Utah Salt Flat Racing Association, Salt Lake City, UT - World of Speed event host
•   BECU (Boeing Employee Credit Union) – School Grant to fund test and data collection software and technology.
Title: Re: T-2011 – what’s behind the number? A CHALLENGE!
Post by: Milwaukee Midget on August 29, 2011, 10:13:34 AM: Okay, ya'll, we've been watching this one come together.

Target 550's ponied up transport, and this team, a team of High School students, are going to the salt, with a car of their own creation.

http://live.gfalls.wednet.edu/ecoteams/

On the middle of the left hand side of this page is a donation form. Mike, expect a check from me before the end of the week.

I challenge everyone else who has watched this build to do the same.

On the form is a note for a "Gift of Honor". This check will be in memory of my High School shop teacher, Aaron Thompson, who taught for years at Linn-Mar High School in Marion, Iowa. Mr. Thompson helped me get my first car, a 1962 T-Bird Convertible, roadworthy and safe. He also restored a beautiful '55 Bird, and like myself, had a disdain for Chevrolets. :wink:

He was a kindred spirit, and a good mentor.

The team is going to be leaving for WOS next week, so don't delay.

Post by: Freud on August 29, 2011, 11:03:16 PM: Marlo Treit, Dick Milne and I went to Granite Falls HS this afternoon to meet with Michael Werner regarding transportation for their car and equipment to WoS.

It's still summer vacation time but Michael was there working with students Tim Wilson and Katie Jackson on their car.

It's no different than any race project: as time draws closer there is still a lot to do. I'll be posting some fotos soon. It is a project for

all of us to support. Part of the Target550 team will be there to support their effort. It's not a speed trial for them. It's a data gathering project

and the USFRA has graciously allowed them to participate.

THANKS USFRA.

Post by: Schruiber on August 30, 2011, 12:07:02 AM: It was great to have Marlo, Dick and Freud out at the shop today, got some good input on little things to make sure we pass tech with flying colors and have many good runs. As Freud said in his post, we are there to raise awareness for alternative fuel, gather data (lots of data) and make it educational. Now we figured on paper if we use a 72 tooth rear sprocket and do a ("student slave labor") push start we could get it going and theoretically reach 57mph :-D

Thank you for your support

Post by: Milwaukee Midget on August 31, 2011, 05:07:23 PM: Just got off the phone with Mr. Werner - what an inspirational teacher. :lol:

They're mid-thrash right now, the students are putting in the time and effort, and Marlo, Dick and Freud have been giving them what I'm sure is solid guidance.

If you're going to make a donation to this effort, I'd encourage you to do so ASAP, as they are unable to accept on-line payments. You'll need to make out a check and send it snail-mail. They'll put your name on the car, if you want, but once it's on the trailer, you might be out of luck.

You've got a few days - they haven't painted it, yet.

Go, Granite Falls Eco Teams!

They've been welcomed with open arms to bring their creation to one of the most unique motorsporting events in the world, at a venue with a history going back almost a century.

And they'll get to work, turn some wrenches, tweak the car, and be up to their elbows and eyeballs making their car better, just like some of the greatest racers in history have done.

Be glad it was an easy fix - clearly a best-practice safety issue for racing - sounds like you were prepped to handle it.

I know, the rulebook doesn't say anything about glass fuel tanks - but then, you're probably the first team to ever show up with one.

Those bug guys are a great lot - nuttier than your standard salt racers, but passionate about their Beetles.

Congratulations, Eco Team! Bump that number up tomorrow.

Curious - I suspect you're running controlled testing for economy - will you be comparing the two gear sets?

Post by: Schruiber on September 17, 2011, 12:00:02 AM: Friday - Day 4 of T2011 on the salt. After a very windy (~24 mph no racing) early morning, we used the time to "tuff" the car and pointed into the free wind tunnel blowing :) some good info was collected; then a few runs, still not the 30++ mph. Upon checking the front wheel alignment (it was off in a "slowing way" we needed to repair one steering arm, so after lunch Tim with a little help of tail wind got a 31.16668 MPH :-D; Next we took of the tail to see and compare - about a mile less per hour. Then we had a great photo session with the largest diesel there; so it's 4 vs. 4000 hp!

photo from yesterday - T2011 and 444 - the caption could read, when I grow up I'll be squeezed smaller and longer......

Evening rain + Mexican food at the truck stop for all 19 people of the T2011 team rounded out the day; we have 4 more runs on our entry, so tomorrow it's the smallest rear sprocket to try for more speed.

Very tired yet very happy

Jasmine changing the rear sprocket "up" to a 62 from a 78 - that ratio and higher inflated tires were going to be our Satuday 9-17 33+mph weapon

Part of the many people who made this possible - L to R Ed Staheli, Nona Larson, Vervia Gabriel, Michael Tuffey and Bob Quarterman

Congratulations on a successful outing. I expect that while the team was unable to get in as many runs as they had hoped, they've still gathered enough info to further this car for next spring's competition.

This is a new beginning - and while the Bonneville event is now in the rear view mirror, please keep us posted on this build diary as to preparation for the Shell Marathon.

Well played, Urban Concept team. :-)

Post by: Schruiber on September 18, 2011, 11:28:37 PM: yes, we are aiming at "T2012". Indeed a lot of data was gathered, both scientific and flying by the seat of our pants; also a good number of those: why didn't we think of that earlier moments happend. Our on-board data has yet to be thoroughly analyzed - we got the AIM system just in time to be installed and working - so lots more work over the next couple of weeks to link it up to video/photo and our notes.

We had a great time and everything went beyond what I had hoped for - I had a lot of people help to make this happen.

Thank you LSR community.

Post by: Schruiber on September 29, 2011, 09:27:08 PM: .....and here a "great read" about Tim Wilson our driver at WOS, written by Jasmine Bates, member on the T2011 team - Enjoy

A Short Story Inspired by the Life of Tim Wilson

There once was a young man named Timmy who liked boats and fish and cars. He didn’t quite know why…those were just his hobbies. Being a young man not yet out of high school didn’t stop Tim from living a vast and colorful life.
Tim’s interest in cars led him to join the Granite Falls High School UrbanAutos Team. Timmy met many interesting people and learned many things, but mostly he worked on the UrbanAutos car, and Urban Concept car built for a fuel mileage competition for high schools and colleges called the Shell Eco-Marathon. When the UrbanAutos first participated their car was overweight and they were not able to compete, but the next year they gave the competition a run for their money. The team left with a new Americas record for Urban Concept Diesel, 186.5 mpg. But the Shell Eco-Marathon wasn’t all the UrbanAutos did, after setting their record they travelled to the Salt Flats in Bonneville, Utah to test their car in different conditions at the annual World of Speed event. They didn’t go as fast as the other cars (not even close) but it was a learning experience and they missed four days of school

---So far this story is factual, but soon it will become much less so.---

On the team’s last day on the Salt Flats it rained rather a lot and the Flats were suddenly transformed into a giant puddle. Tim, being the driver of the car, was not very happy. So what did Tim do? He pulled out his squirt gun and began to pump the water off the Salt. At first his friends laughed at him, Timmy always was a silly boy. But soon their snickers turned to cheers as Tim squirted the water clear over the mountains. A crowd began to gather, and soon other racers wielded their squirt guns and marched out onto the fast drying salt. The mob of squirt gunners grew so large it looked like it was raining backwards. Just as the sun began to rise over the Salt Timmy launched the last drops of water over the mountain. Now Timmy was no longer just a boy who liked boats and fish and cars, he was a legend, a hero to be remembered in racing circles for years to come.

Here are some shots from one of the runs...the first one, I think. It was the afternoon of the 14th.

Micheal, I'll be burning a CD and sending it off very soon...like tomorrow, I hope.

Regardles how serious running at Bonneville appears to be, there is still a lot of whimsy involved. I occasionally need to be reminded of that.

Rest assured, when I return to Bonneville, I will remember to put a squirt gun in my toolbox.

In fact, maybe I'll bring a super soaker.

Tim drove the LSR car in the parade, needless to say it is not rain proof = we were in need of Rain-Ex and Anti-Fog..... ShopGirls' Iron Maiden on the right was trailered, because Sara, our only licensed driver had to take the SAT test - yup, school interferes sometimes.

If you get a chance, drop us an update.

Thanks.

Title: Re: T-2011 – what’s behind the number?
Post by: Schruiber on November 18, 2011, 08:44:25 PM: Chris, after the "WOS High" there is now a low, as it has been every year at the beginning of the school year. Each team, ShopGirls and UrbanAutos has 3-4 new members, which I am very happy about. getting re-started with the new teams is always a challenge.

The UrbanAutos team wants to use part of the "LSR-Long Tail" to improve the aero at the Shell Eco-marathon - the handicap is that tail is about 25 lbs heavier than the short tail; using the full belly pan makes venting the hot air in the engine compartment a problem to be solved. In order for both teams to test their improved aero we need to finish the wind tunnel, and at the same time learn more about Solidworks software and the Cosmos component which allows CFD.

Stay tuned......
Title: Re: T-2011 – what’s behind the number?
Post by: Schruiber on February 20, 2012, 10:56:23 PM: I know we have been very quiet for some time, yet a lot is going on. Now it is down to 37 days until loading the cars to go to Houston for our 3rd annual Shell Eco-marathon fuel efficiency competition - the Urban Concept car is getting new and much lighter wheels (Pro-Wheel) which will save us about 40 lbs over the Kymco wheels with Pirelli Diabolo tires. To make the most of our weight loss we decided not to use part of the Bonneville long tail, but to improve the current short tail according to "Kamm Tail Aerodynamics". Lot's of mock-up, math and learning in this one; we looked-up cars that have those kind of tails (I once had an Alfa Romeo AlfaSud that had such tail!). The center structure with the gull wing doors do not allow for the ideal adhesion to the Kamm formula, yet it will be as good as the current geometry allows - attached are a couple of photos in progress; a lot of the old body will be cut out, we only keep a skeleton underneath. Materials used will be a combo of 3/16 foam board, 1/2" styro foam (left over from the LSR long tail) and 2mm uni-directional plywood, all covered with 6 oz. fiberglass, using epoxy resin.

Of course corrosion control after World of Speed was a huge task, we still have some rust and "white powder" aluminum; but it will be gone soon!

Stay tuned...........
Michael
Title: Re: T-2011 – what’s behind the number?
Post by: Schruiber on March 11, 2012, 06:19:14 PM: Another week has gone by and lots of things came together......

Since we have a new and much lighter set of wheels sponsored by Pro Wheel, we chose to make them interchangeable with our current Kymco wheels - now the new wheel have the Michelin High Mileage tires mounted to run in the Shell Eco-marathon; the Pirellis we will use to run everywhere else including World of Speed later this year again.
The new and also lighter brake discs were designed by the students in SolidWorks with the help of Bob Quarterman our engineer volunteer. then they were laser cut from stainless at one of our Tool and Die Maker volunteer Ed's industry partners by his son.
Students machined new rear alu hubs; the whole rear axle, freewheel and differential were overhauled (it had salt damage) and freshly installed. Because we now run a fully enclosed engine compartment, a fresh air intake for engine made from dryer vent tubing and a cooling air duct made from scratch by using insulation foam for the mold and fiberglass for the part are now in place and ready to be tested.
The Kamm-modified rear body is ready for fiberglass work, putty, sand and paint.
Parallel the ShopGirls car had the drive train "beefed" up to prevent movement that led in the past to dropping the chain! And best of all we still have one and a half weeks to test and revise ...... yeah but still overtime!

We also had a nice article and photo gallery in our local newspaper - http://www.heraldnet.com/article/20120308/NEWS01/703089906

Title: Re: T-2011 – what’s behind the number?
Post by: bucketlist on March 14, 2012, 01:07:51 AM: re the Kamm tail: Seems to be based on the misconception from Detroit where they simply cut off the car where the equipment stops. Forbes Aird in Aerodynamics for Racing and Performance cars explains Dr. Kamm's concept and shows an example. It's copyrighted or I would include it here. Kamm abbreviated the tail where the body section is about half the maximum. Then it's not square, everything is smoothly rounded.
Title: Re: T-2011 – what’s behind the number?
Post by: Schruiber on March 14, 2012, 10:58:22 PM: wow - 10001 hits on our T-2011 thread; thank you all for your continued interest in our endeavor; needless to say it's been a very interesting "ride" on the fringe of public education, yet we reach a great number of students, expose them to opportunities, get them engaged and show them pathways towards careers. It's very hard learning made fun!

bucketlist - you are right, our Kamm tail is rather square at this stage. The students researched it thoroughly looked at many pictures including the pre-WW2 BMW 328 and the latest VW L1. Then we had to compromise because we did not want to build a complete new short tail, and not cut our "LSR Long Tail" to the maximum allowable length for the Shell Eco-marathon, although we provided a 2 bulkhead split line to allow for this. Main reason was it still would be heavier than the modified short tail. It also would offset any weight loss gained by using the new Pro Wheel/Michelin set-up.
Our center section gullwing doors did not allow for a gradual reduction from the full cross section to 50% over the rear 55% of the car. Rounding over the rear section will take more time than we have left before testing (this weekend) and loading the cars to go to Houston, next Thursday. Remember these are educational projects and there is a lot of learning left in our cars. We always appreciate forum input as it challenges the kids to continue to be innovative and on the up-and-up. I will buy the book you mentioned

Predictably after Houston with 112 teams fielding 130 cars this year my students will want to build new cars...........stay tuned :-D

Both Hunter and Jasmine drove it around the school house; it was Jasmine's first drive. In the first photo you see how the gull wing doors limit the length of soft curve we could apply to our modified tail.

Now that it runs there is time to check one other "important" thing - our "Under Glow LED Bling". Hunter gets a helping hand from our volunteer Bob.

Barely visible through our new Pro-Wheel's are the stainless brake disks - too bad they will be covered by hub caps! Or should we have real Moon's? :lol:

For the girls's car, Dansil and Katie are making new lighter chain guards from carbon fiber panel that is left over from the Urban Concept car doors. It's flat panel kerf cut and glued with expanding Gorilla glue, then glassed on the inside for add strength.

Sara in the mean time Sara is running the car over simulated bumps to verify those won't have "the power" to have the chain come off, a problem that happened last year. Ed our machinist volunteer added the long pole + Swiss flag so the car is seen in the parking lot by regular drivers; top speed attained was 41mph before they ran out of school parking lot :-)

I don't give out contributions lightly - since the money is from contributions you folks have sent to me to keep the site going. In this case I figger you'd be okay with it -- since it's not likely that a whole bunch of you would up and mail stuff or money to the group.

ShopGirls 4th place in the Diesel Prototype category with 520MPG (+10.6%) 1st-1290MPG; 2nd-703MPG; 3rd-683MPG. Yet the Girls won again top honors int he safety award = $1000 check!

UrbanAutos 2nd place in the Diesel Urban Concept category with 231MPG (+24.2%) 1st-489MPG.

1st photo shows our urban car in front of the staging lane - diesel winner is the 3rd car, a small, half our weight little single-seater roadster from Louisiana Tech. I hope Shell is adding a mandatory 2-seat requirement for 2013, yet nonetheless this competition has shown we need more sophisticated cars and engines in order to stay competitive. You see the girls lime green car on the track in the upper left.

2nd photo - Tim and Hunter changing sprockets; "Philippe the Firewall" our mascot grew a mustache while in Houston.

Spring Break now - our next events

April 14 - PACCAR Technical Center Open House; we will be displaying both cars next to the ones from Western Washington University's Vehicle Research Institute and the University of Washington

April 22 - both cars for Earth Day at the Future of Flight Museum in Everett

Look at our website calendar for links http://live.gfalls.wednet.edu/ecoteams/

Of course we will be at World of Speed in September - I think the girls want to bring their car too to see how fast "Iron Maiden" will go (they reached 41mph in the school parking lot before running out of parking lot :-D

This last Saturday both teams showed their current cars and some future car ideas at the Vintage Aircraft Weekend; then it's back to school Wednesday, classroom only, no Bonneville trip this year as any fundraising is going towards making the cars more competitive looking seriously at improving the engine and drive train, since we still have stock engines and so-so drive trains. It will require testing, testing, testing and parallel applying the learned to designing and building new cars, which may take us until the 2014 Shell Eco-marathon race. Part of that testing though is planned for the 2013 World of Speed; I will be there this weekend for WoS. Look forward to seeing old friends and making new ones.

Improvement focus this season is the engine and drive train. As part of the improved air intake we are making velocity stacks; this is the 1st off prototype made from schedule 40 PVC 1.25” diameter pipe, a male form turned on a Mini Jet lathe from a 2x4 glue-up and then while spinning it at 500 rpm heated gently with a heat gun.
The exact lengths and shape has been calculated by the students for a variety of altitudes and air temperatures, using formulas found on the internet.

A small engine dyno is going to be built to test and fine tune our 2 small diesels. I might have questions to that topic in a separate thread.

Chain drive is planned to be replaced by a belt drive.

Stay tuned….

Post by: Schruiber on March 30, 2013, 12:42:23 PM: Next week will be our 4th time at the Shell Eco-marathon Fuel Efficiency competition in Houston Texas. This now 4 year old car keeps changing and is providing excellent learning. With lots of overtime and great hands-on experiences for the students in our industry partner and volunteer Ed’s machine shop we upgraded the Urban Concept car’s rear engine compartment ingredients.

- We replaced the whole rear steel tube frame, engine with its CVT belt drive and:
- Moved firewall forward and took advantage of the space under the seat.
- Aluminium frame machines and fabricated from extrusions and tubing.
- Single wheel drive and aluminum axles eliminating the differential and steel axle.
- A new Yanmar L48 210cc 4.5hp diesel engine.
- A tuned velocity stack with intake air temperature sensor; exhaust is now strait up which makes it quieter
- Machined off the flywheel forced air cooling fins and replace it with a thermostat controlled electric fan to keep it hotter = less fuel
- Very light weight (and high $$) Lithium MC-battery
..... and, taa-taaaa strait coupled it with a 5-speed transmission from a 250 cc Yamaha – thus the 3rd pedal.
8 points of data including 3 way acceleration/GPS are collected with an AIM EVO4 and displayed on a MyChron3 Dash.
With losing weight and gaining a transmission we are still ~25 lbs lighter than last year at just about 408lbs.

It is now a “drivers” car – our two drivers Brooke and Hunter are already betting on who will set the higher mileage. No prediction yet because after just a few laps for each and some debugging it went in true race fashion onto to the trailer bound for Houston!

It sure ticks over nice in 5th and has the “right speed”. Wondering how fast it would go on the 130/150 track at WOS?

Stay tuned for the link to the documentary film Shell has made about our car program and educational outreach to Elementary and Middle school students.
