A METHOD FOR PREDICTING THE AERODYNAMIC LOADS AND DYNAMIC RESPONSE OF ROTOR BLADES

Abstract

A method for predicting the aerodynamic loads and the flapwise bending moments experienced by the blades of a rotor in steady translational flight has been developed. The blade representation which is used satisfies the chordwise aerodynamic boundary condition, and a simplified discrete vortex filament representation is used for the wake of each blade. An iterative procedure was developed which yields a simultaneous solution for the aerodynamic loads and dynamic response experienced by the rotor blades. The lift loadings and bending moments were computed for two flight conditions of the H-34 and HU-1A rotors. Comparisons of these results with measured results are presented as time histories and radial distributions of the harmonic components.
