Nonlinear Rotorcraft Analysis-Experimental and Analytical
Abstract
A parallel effort involving both analytical and experimental work was performed to allow a deeper understanding of the limit cycle behavior of rotorcraft and of the implication of this behavior for the safe operation of such rotorcraft. The theoretical development encompassed articulated and hingeless rotors with a great enough number of included degrees of freedom to allow accurate predictions of a simplified rotorcraft's responses. The experimental model allowed the simulation of both hingeless and articulated rotors in ground resonance. The purpose of the above work was to identify the regimes of helicopters operation that can support limit cycling and the range of excitations the system can withstand before entering a limit cycle.
