Does Aileron setting increase drag ???
Hello,
Talking about aileron increase the drag when they are 1 inch up. Because the angle of attack change thu the elevator produce more drag to keep up the altitude.
I don't think so, remembering when I've flown glider, we use the flaps as little as 3 degree up to increase speed. That doesn't affect the drag. But with an aircraft is different because you need to keep an altitude.
So this is my point of view for an aircraft set with a normal CG position (in the middle of the graph):
If the ailerons are 1 inch up (reference of the trailing edge of the wing), your speed is increased to keep the same amound of lift, because the camber of the wing is less (in the area of the aileron only). The angle of attack of the elevator change a little to keep the altitude but its arm is so far I think the drag of the elevator is negligeable.
The aircraft is a convair 580. flying at 278 TAS @ FL200, with passagers.
Thank you for your help,
Raf
