Keywords: aerodynamics, structure dynamics, unsteady loads
The paper concerns numerical simulations of a non-linear elastic rotor system included in a deformable helicopter frame coupled with an aerodynamic model for predicting forces and moments on the rotor blade. With such a coupling the behaviour and performance of the helicopter Skeldar V200 have been predicted.
