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 effect of airfoil geometry on dynamic stall is quite intricate. As is shown in the figure, for a cambered airfoil, the lift stall is delayed and the maximum nose-down pitch moment is significantly reduced. On the other hand, the inception of stall is more abrupt for a sharp leading-edge airfoil. [8] More information is available here. [13]
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.
A Yeti Airlines crash in Nepal that killed 72 people almost a year ago was caused by the pilots mistakenly cutting power leading to an aerodynamic stall, a report issued by a government-appointed ...
Crash occurred at private Buena Terra Airport. An autopsy conducted by the Shawnee County District Coroner's Office concluded that Stucky, 74, died of multiple blunt trauma injuries, the NTSB ...
The incident was found to have happened after their EV-97 EuroStar light aircraft experienced an aerodynamic stall after descending too steeply.
On aircraft with swept wings, wing tip stall also produces an undesirable nose-up pitching moment which hampers recovery from the stall. Washout may be accomplished by other means e.g. modified aerofoil section, vortex generators, leading edge wing fences, notches, or stall strips. This is referred to as aerodynamic washout.
The plane violently oscillated up and down and the "stick pusher” activated, the report said, meaning the onboard computer thought the plane was in danger of an aerodynamic stall.
