Did you know?
The dynamic stall is one of the hazardous phenomena on helicopter rotors, which can cause the onset of large torsional airloads and vibrations on the rotor blades. Unlike fixed-wing aircraft, of which the stall occurs at relatively low flight speed, the dynamic stall on a helicopter rotor emerges at high airspeeds or/and during manoeuvres with high load factors of helicopters, when the angle of attack(AOA) of blade elements varies intensively due to time-dependent blade flapping, cycli… WebJust like how an airplane's wing can stall at lower speeds, the same can happen to the retreating blade of a helicopter. However, unlike planes, in helicopters this occurs in high-speed flight. In ...
