The influence of unsteady aerodynamics on the frequency-response of a hovering rotor
The influence of unsteady aerodynamics on the frequency-response of a hovering rotor
A recently developed new unsteady aerodynamic model of a hovering rotor (TEMURA) is used to investigate the influence of unsteady aerodynamic effects of the frequency-response of a hovering rotor. The study includes four bladed hingeless rotors that differ in their first rotating flapping frequency. The influence of various effects is investigated and discussed. In general variations in the intensity of the circulation of the trailing vortices have the largest influence. The theoretical results exhibit good agreement with experimental results from the literature.
