In generic terms, a stick pusher is known as a stall identification device or stall identification system. [73] A stick shaker is a mechanical device that shakes the pilot's controls to warn of the onset of stall. A stall warning is an electronic or mechanical device that sounds an audible warning as the stall speed is approached. The majority ...
The pilot applies full aileron, then rudder in the opposite direction and full down elevator. The plane will "snap" and then the pilot must neutralize aileron (and in some cases apply aileron in the same direction as the rudder) and the plane will be in an inverted flat spin. Pop-Top Same as a blender, but going up. The pilot must have a good ...
Rotor map of dynamic stall locations for all conditions. Stage 4: full separation of the flow on the upper surface of the airfoil can be observed, accompanied by the peak of nose-down pitch moment. Stage 5: the full flow reattachment is achieved as the AoA gradually decreases until it is fairly smaller than the static stall angle. [10]
In a normal spin, the wing on the inside of the turn stalls while the outside wing remains flying. It is possible for both wings to stall, but the angle of attack of each wing, and consequently its lift and drag, are different. [3] Either situation causes the aircraft to autorotate toward the stalled wing due to its higher drag and loss of lift.
Coffin corner (also known as the aerodynamic ceiling [1] or Q corner) is the region of flight where a fast but subsonic fixed-wing aircraft's stall speed is near the critical Mach number, making it very difficult to keep an airplane in stable flight. Because the stall speed is the minimum speed required to maintain level flight, any reduction ...
A stick shaker is a mechanical device designed to rapidly and noisily vibrate the control yoke (the "stick") of an aircraft, warning the flight crew that an imminent aerodynamic stall has been detected. It is typically present on the majority of large civil jet aircraft, as well as most large military planes.
The angle of attack can be increased to compensate, however beyond a certain point the rotor blades stall and lift rapidly decreases. Rotor stalls are not recoverable because the descending helicopter has airflow moving upwards through the rotor disc, so even full down collective will not restore normal airflow. When the helicopter rotor stalls ...
In the slip, the raised wing — the left one if the airplane is turning to the right — will stall before the lowered one, and the airplane will reduce the bank angle, which prevents the stall. In the skid, the lowered wing will stall before the raised one, and the airplane will tighten the turn, and the stall can develop to a spin.
