North American Eagle events

[racefanwfo]

To answer your question john i use to go to LACR every year for the JET CAR world finals and a good running JET DRAGSTER would run the 1/4 mile just over 5 seconds at about 300mph or a little more. NHRA limits JET DRAGSTERS to 320mph on there tracks. I have been told that if there was no speed limit and a long enough shut down a JET DRAGSTER could run 350mph in the 1/4 mile. I was also told by one of the drivers that they almost always click the engine off and pull the chute right at the timing lights.

Next time we come out, hopefully Mike Cook will be able to show up with his clocks and
we will have some officials on site.

I read somewhere that you were using Cook's clocks.  If you were not, then how were you timing your runs??

We are using Topcon technology. We have the license rights to use it up to 1000 mph. It is accurate to within .20 of an inch.
We pull off of 19 satellites and usually about 9 or 10 of those are Russian. We can pin point the runs so it is measured over
the exact measured mile for each direction. Two years ago we installed our Topcon equipment on my lakester and ran it
at Bonneville and the speeds were identical. We will provide the date, first, to the engineers at Topcon to validate our
results. With data, video and witnesses, we can "claim" the speed for Guiness records only. Otherwise all we can claim
is that we exceeded Lee Breedlove's speed and that is all. It is only a benchmark to so the world that we are serious
contenders. On one run alone, I ran 450 knots indicated on the air speed indicator (515 MPH). We use that data mainly
to validate our aerodynamic modeling of the Eagle so our aerodynamicist, who is conducting our CFD work can better
understand the air flow around the fuselage. Anybody who in involved in land speed racing (or flying airplanes) knows that
stability and control is the key to success. That is what this particular session was all about.

So the calculations are time over measured mile rather than instantaneous speed readings direct from the GPS.

Topcon should be able to verify the speed calculations with time stamps and checksums on the NMEA data sentences logged (guessing in the nmea as its the most common GPS data logs).

Guessing your using RTK with your own base to get that accuracy, going dual chip with GPS an GLONAS should be giving good reliabilit.

Good to see successful runs, where to from here?

The Eagle will be back in it's nest for a while so we can clean it up, make a few changes and improvements then look forward to
getting some "official" runs next summer for Jessi and me. Once we feel we can get the job done and get permission to run
somewhere with enough distance, we'll get ourselves set for the attempt at the big number. It takes $$ to get into that next
category.

Hurry up and wait.
Speed events are the slowest form of racing.
It doesn't matter what sport, eh?

Good luck in 2014 or 2015 NAE.

Watch your backs.

Ed,

I think the negative comments were simply as a result of the unexpected references to Lee Breedlove's 1965 speed and talk of a "record" and nothing more. Certainly Jessi did a great job with limited seat time and the final speeds achieved at Alvord were a worthwhile stepping stone hopefully to something more next year.

Regards,
Phil

If the speeds are legit.... a good first outing. The car appeared to handle well, no surprises in any of the systems... and it was safe. A good test session.

[F104A]

Thanks Aliso Bob. We have gone out for several test sessions in the past and had to work on solving issues. This time, we stayed for two weeks
and worked on the problems on site. Our basic mission was to get some smooth strong runs so our aerodynamicist, Darren Grove, to match the
sensor data to his CFD modeling. The secondary mission was to get Jessi some seat time so she can go after the benchmark set by Kitty O'Niel.
Once we have finished this items and all systems are go, we will be scheduling ourselves to go after that big record of 763. I want to say
Thank You to all who have supported us along the way. It is not easy and with support from our fellow Americans/Canadians, we will push
even harder to get that record away from our friends, The British.........Ed

Keep up the good work Ed, you are getting there.

Nice updates. Best of luck. Looking forward to the next chapter.

Sounds like a huge step was made. Congrats and good luck for the future.

"Jessi Combs has become the fastest woman alive" is the opening sentence.

Did they kill Sandra Bullock?
