These compensations can only do so much. Increasing angle of attack to compensate for reduced blade airspeed has the effect of maintaining lift only until the point where critical angle of attack is reached, after this point lift sharply decreases. All airfoils have a critical angle of attack (also called a stall angle of attack) which is the angle of attack that produces most lift. Above this angle flow over the airfoil becomes detached and lift d… WebApr 11, 2024 · The wing can be made to generate lift by reducing the angle of attack to an appropriate level.

WebJan 30, 2024 · Your stall speed decreases because the C L M A X of the wing increases with flaps deflected. Deploying flaps increases wing camber and increases both C L and C D at the same AoA and airspeed. Depending on the type of flap, the critical AoA actually reduces: the airfoil with simple flaps deflected stalls at a lower AoA than without flaps. WebNov 12, 2004 · In a fixed-wing aircraft, you can unload the wing without serious consequences. In fact, you may want to unload the wing to prevent a stall. This can happen if you push the stick forward at the top of a zooming climb or at the top of every porpoising cycle if you let the aircraft get into pilot-induced oscillation (PIO).
