HQ35/12 Airfoil
Happy Days:
Okay,.............Thanks Fred, and you other guys, for replying. I must go away and think about this. It's all very interesting stuff. Hmmmmmmmmmmmmm.................!
Fred:
You're welcome ! :D
btw, forgot to say, Fernando, in a shockflyer, this is the incidence of the wing that create the lift (well, sort of lift, I will more call that a air deflection :P ), not the "profile". :D
Happy Days:
So Fred, you're saying that the shockflyer merely deflects air in one direction and the wing "reacts" in the opposite direction? like a rudder perhaps?
Fred:
Exactly ! :D
The wind speed at the top and bottom are the same (flat), no lift generated, only drag.
Change the incidence, and you will go up or down. :D As you say, abit like a rudder / elevator or your hand through the window of your car in good speed ! :D
Happy Days:
I'm thinking of a symmetrical wing. the camber on the top is equall to the camber on the bottom. Assuming zero angle of incidence and zero angle of attack where does the lift come from?
