摘要

Based on blade element/momentum theory, the aerodynamic impact on rotor controls and blade flapping caused by a straight-line vortex penetrating orthogonally the plane of a rotor disk is solved using a realistic swirl velocity profile. The collective and cyclic controls needed for disturbance rejection and the coning and cyclic flapping motion developing are computed.
