摘要

Abstract

The multi-body analysis of the aeroelastic stability of the tiltrotor aircraft is presented. Multi-body dynamic differential equations are combined with the equations of the unsteady dynamic inflow model to establish the complete unsteadily aeroelastic coupling analytical model of the tiltrotor. The stability of the tiltrotor in the helicopter mode is analyzed aiming at a semi-span soft-inplane tiltrotor model with an elastic wing. Parametric effects of the lag stiffness of blades and the flight speed are analyzed. Numerical simulations demonstrate that the multi-body analytical model can analyze the aeroelastic stability of the tiltrotor aircraft in the helicopter mode.
