Abstract:In this study, the aeroelastic analysis of rotorcraft in forward flight has been performed using dynamic wake model to handle unsteady aerodynamics. The quasi-steady airload model based on the blade element method has been coupled with dynamic wake model developed by Peters and He. The nonlinear steady response to periodic motion is obtained by integrating the full finite element equation in time through a coupled trim procedure with a vehicle trim for stability analysis. The aerodynamic and structural charact… Show more
