Aeroservoelastic Analysis of Rotorcraft-Pilot Coupling: A Parametric Study

This paper presents preliminary and intermediate results of a collaborative effort aimed at investigating Rotorcraft-Pilot Coupling from an aeroservoelastic viewpoint. It focuses on the coupling between helicopter dynamics and aeroservoelasticity with the passive, i.e. unintentional, behavior of the pilot, that closes the loop between the vibratory motion of the rotorcraft and the control inceptors. The objective is to determine the parameters that mainly affect the phenomenon, to infer design guidelines in order to limit the insurgence of related issues at later stages of development.
