Steering Rules
« on: April 15, 2019, 05:45:33 AM »
Until my rule book(s) arrive I'd be interested to know if aero-steering is allowed in lieu of angular movement of tire/wheels for unlimited streamliners?  If wheel steering is required is there as distinction between the steering axle...example: is rear steering allowed;  also is there a minimum angle steering wheel(s) must turn?  Thanks...

Aero steering will never fly. For so many reasons.  Rear steering would need a lot of demonstration, I bet, Has not worked well in the past. Is this for a FWD car? Corvair powered? Most 'liners don't turn much.

Though I didn't find the rule with quick look, I think rear steer is prohibited. Rule 3L says in part: " Steering shall be assured by at least two (2) front wheels."

Breedlove tried it with the Spirit of America 3 wheeler. It didn't work for him.

Some one in the past had a rear steer car. He said it was so bad that the next pass would be straight to the dumpster.

Maybe I'm missing something, but I think about the times I've damn near flipped forklifts , and I simply can't imagine why anybody would so much as proffer the idea of rear wheel steering in an LSR vehicle.

I figure it was because they saw the advantages of not having the complexity of steering a front-wheel drive.

Playing Devil's advocate here..... But there was a rear steer LSR car that went 763 MPH.  :evil:

Of course it did have computers to help with the control.  8-)

Thanks everyone for your responses.  Rear steering is not something I'm advocating for, just asking to learn all my options.  My body design has such a narrow front there's no room for conventional steering.  The max I can eek out with M/T 24.5x7.5x16 tires/wheels is 6 degrees lock to lock from a leading pivot wheel frame section.  I'm designing a fore and aft front wheel arrangement similar to Speed Demon and others.  I'm thinking at a modest speed (say above 150 mph) a vertical nose fin should provide adequate surface area to control L/R steering movement of the liner.  Anyone ever tried that?  Thanks...

A vertical fin on the front, moveable or not, moves the center of pressure forward, a circumstance that is undesirable.

6 degrees is more than enough. Ask Marlo, Danny Thompson, Nish, Vesco...

Find Jack Costella on Google and ask him about narrow fronts that steer up to 400 mph. And also slowly when rolling up to the start line. Very helpful.

The Vesco liner has 6 degrees of steering 3 each way.. A lot of cars had to slow down their steering after a few runs as they don't want quick steer.
