Slots increase the stalling angle of attack by

but with the wings at an angle of attack that may exceed the stall angle. Stalling at high-speed gives a more dramatic effect than at low speed. This because the strong propeller wash causes one of the wings to stall first. that combined with the high speed produces a snaproll followed by a spiral dive.

Angle of attack at various speeds. constant ... increase in the AOA will result in the wing stalling. Therefore, ...... Therefore, leading edge slots, slats, and flaps are used to.

As weight of the airplane increases the stall speed does increase.Due to the greater weight, a higher angle of attack must be maintained to produce the additional lift to support additional weight in flight.Therefore the critical angle of attack will be reached at a higher airspeed when loaded to...

aerodynamics - How does stall depend on angle of attack but ... $\begingroup$ When you say "angle of attack is 17.46 degrees farther away from stalling" I think that is a bit confusing. You could clarify that that aircraft is now pitched upwards 17.46 degrees, but the angle of attack does not increase by that much. In fact, AOA would decrease, right? $\endgroup$ – fooot Mar 31 '14 at 16:04 Angle of attack - Wikipedia In fluid dynamics, angle of attack (AOA, α, or ) is the angle between a reference line on a body (often the chord line of an airfoil) and the vector representing the relative motion between the body and the fluid through which it is moving.

As the angle of attack increases, a symmetrical wing produces more and more lift, but the buffet increases too. The only way to keep the T-38 in a niceThe Angle of Attack indicator said we were nearing a stall though the airspeed indicator was steady at what should have been a flyable speed.
