This will be hooked to a small carbon fiber accumulator tank from a paintball gun. Then I have a dual acting three way solenoid that will feed the pair of these cylinders. The air system is going to control wing pitch in a fraction of a second for behavior similar to a McLaren wing. However, because of the odd shape of this car it needs WAY more height to be effective. For that the LACT units will be responsible for gradual extension and retraction of the wing like they currently do on my V 1.0 wing. The difference is after I add the air actuation the wing pitch will no longer be tied to height.
@@dodadscarworks973 Wow. Thank you for the explanation. Fraction of a second response time is incredibly impressive. I hope we get to see the testing phase of V 2.0 active wing 😎 All the best man 👍🏽
Cool! Why do you go for a pneumatic one instead of an electric one? I buy old electric wheelchairs sometimes and you can find them with lineair actuators.
I already have LACT electric linear actuators on the wing. They do pitch and height. But, they are too slow to do pitch control for active aero braking. The wing takes about 1 second to go from low drag to full aero brake. That's nowhere near fast enough to dynamically respond to brake and accelerator actions. The LACT units also have a maximum duty cycle of 20%. So they would not survive long doing continuous positioning. That's a task for hydraulics or in this case pneumatics due to weight.
It's pretty quick 😎 will it be used for the rear wing/spoiler ? thanks for sharing.

Did you do a calculation on the force needed?
@@vdtogt You bet! Plenty of force at speeds that it may see at the track.
