Powered rear wing

[old-git]

I have just bought a replacement spoiler motor assembly for my daughter's Corrado and I got to thinking.........it may be useful to make any wing that I may have to fit to the Elan adjustable either from the cockpit or by vehicle speed or both. This would allow the wing to be feathered during high speed runs and to assist in high speed braking.

Any thoughts and/or suggestions as to a better motor assembly I could use?

You could also use it as an air brake!

A 2 stage is a good idea, increasing the downforce with speed makes sense. Are you worried about the extra weight though?

good idea dont know how hard it would be to do however

I'm not sure the adaptability would justify the extra weight, otherwise someone else would have done it all ready.

You really need to read my thread properly

The weight of the mechanism is only 2kg and will be behind the rear wheels, so will aid traction. I would hope that this plus being able to adjust downforce will more than compensate for the extra weight.

It has been done, Bugatti Veyron for example. Most, racing classes have banned inflight movable wings and spoilers. However, I am not aware that TOTB has yet

If it's adjustable with speed then any downforce it generates would have to be taken fought against by the servo?

I've always wondered how they get round that, I think the Veyron system is hydraulic though.
Just thinking, if you wanted a two stage wing you could make it spring loaded, so it's set for down-force off the line & then can be moved to an air-brake position in one move. Then it just needs resetting before the next run.

veryron is hydraulic as is the merc SLR iirc
nothing to say the servo couldnt run the valves and have the system under pressure

I think that a minimum amount of air circulation would be needed for wing / spoiler
to be effective. How fast you go ?

The Mk1 & Mk2 GTO's have active aero's front and rear. They go up at 50 mph and down at 30 mph.
These do rely on quite a lot of electrics, the system has it's own ECU and they pick up a signal from the speed sensor, but they are switchable from on/off so in theory the motor from the rear aero could be controlled by an independent supply and switch.
