Suppression of Transmitted Harmonic Rotor Loads by Blade Pitch Control
Abstract:A study is made of the possibility of using higher harmonic pitch angle inputs to suppress the transmission of oscillatory vertical forces from a helicopter rotor to its driving shaft. The aerodynamic loads that are the source of the objectionable forces are computed using a realistic model which represents the rotor blades by bound vorticity distributions and the wake by a mesh of segmented vortex filaments.
