description abstractThe term “air resonance” refers to an instability associated with helicopters in hover. It is characterized by a coupling between motions of the fuselage and the blades and is of primary concern for helicopters having soft in-plane rotors. This paper presents a study of the effects of nonlinearities on the dynamical behavior of a simplified air resonance model. In order to provide a direct comparison between the behavior of the linearized system and the nonlinear one, a linear analysis of the air resonance model is first performed. Then, the system is analyzed for the effect of selected nonlinearities on its steady state dynamical responses. Geometric nonlinearities and cubic lag damping are considered in these analyses.
