WebIn most phases of flight that coning angle/force is going to be pretty constant, depending on what the aircraft is doing. Flapping directly corrects for dissymmetry of lift. The velocity of an airfoil has an exponential effect on the total lift it generates. WebAnswer: R22 ROTOR SYSTEM by Frank Robinson I have read various explanations in this forum attempting to explain the dynamic and aerodynamic characteristics of the R22 rotor system, especially the 18-degree delta-three angle designed into the R22 swashplate and rotor hub.
