Pork Pie and and I were visiting in 08 and I told him I wanted to build a simple car that could take advantage of the skin from tanks that I HAD,  this is what we came up with.  Now it remains to be seen if we can make something "we all" might recognize when we get through with it here in my back yard ---we hope to have web site where we can post photos to soon.

Good point...ya might be able to make it a 3-motored liner.  Are ya goin after Nearburg's records?  AA/GS looks "doable."

Go get 'em, man!

no we dont---that mid bay will be full of STUFF like two heat exchangers, an oil tank for both engs, a fuel tank for both,  a plenum area for each eng. and maybe water for each eng.

Bloc Cuadriculado ---ie a 1/4" sq in scale planning pad that I switch back and forth with a sq. representing 2" and 6" and the shop floor, the lakester, and varius components,  with a 30 ft tape. a st. edge and a compass.

Robbie,,

Them guys Pork Pie and Sparkey  sure have them fancy design tools,,, Makes our plain white paper, a protractor and a #2 pencil look old fashioned,  LOL

Sparky, PP  keep us updated,,,, looks pretty cool

Both engines sharing a common oil source?  Maybe I'm over-thinking this, but if one were to go, don't you risk contaminating both with shavings?

I run an Oberg on the return line now and another one in the feed line now and conventional one before it goes into the block.

Cajun Kid,
I use the same level of technology as you do, it's called "Pencil CAD" been doing it for over 40 years. I have a drafting board next to the area that I build stuff in and when I get stuck I get out the scale, T square and no. 2 and work it out. If you recognize the name Adrian Newley, the designer of the Red Bull Formula One car, you will be happy to know that he still uses a pencil and drafting board and leaves the CAD work to the "bit" heads.

Sparky,
  I see you have a signature Pork Pie vertical stabilizer! :-)  Looks slick. Have fun building it.

Rex,
  Concrete floor, soap stone and full size scale in use here.

Since you're in the design concept phase of this build, do you mind if I throw out a thought that's been bouncing around in the empty space between my ears for a while? Please keep in mind that I'm a bike guy with very little LSR experience even in that, and feel free to discard anything I may come up with, like I said, it's just a thought.  :-)

Side wind forces are always a concern, since it is impossible to plan on getting a run with absolutely no wind. Side winds have the effect of creating uneven aerodynamic forces side to side and destabilizing the vehicle, and possibly adding drag as well. Aircraft deal with this problem by "crabbing" in flight, keeping the air flow straight down the fuselage and the forces balanced.

Why shouldn't streamliners be designed to do the same thing? If the rear suspension was designed like the front, with provisions for the wheels to have a small amount of self steering, it would allow the car to "weather vane" and self adjust to small side winds that are encountered during the run.

Of course, for this to work and be safe, the caster, camber, and toe would all need to be carefully thought out, and the total steering angle would have to be very limited, with the action heavily damped to prevent it from going into a tail wagging situation. The actual steering would still be done by the front wheels, and no doubt the driver would experience a different sensation with the rear of the vehicle moving off center, but probably not any worse than that of driving a car down a gravel road.

A 4MPH side wind at 200MPH would be a 2% ratio, and it would get smaller as speed increased. Allowing the rear of the vehicle to "weather vane" just a couple of degrees to either side would seem to be enough to maintain airflow straight down the body, which would eliminate side loading on the tires and potentially make the vehicle more stable, if my idea is any where close to right.

So, what do you folks think? Am I completely full of crap here?  :cheers:

Ah, this is obviously some strange usage of the word 'safe' that I wasn't previously aware of.  Douglas Adams
