Inverse Simulation for Helicopter Maneuvering Flight

  • Received Date: 07 Jul 1999

  • Inverse simulation and analysis of the representative maneuvering flight for the current helicopter are presented.The more sophisticated nonlinear model of flight dynamics,which include non-uniform inflow model,nonlinear aerodynamics of fuselage,rotor flap motion and forces coupling with the motion of helicopter body,is considered in inverse simulation.The algorithm of inverse simulation is proper to the above nonlinear model,and the assembled iteration method is used to solve generalized nonlinear algebraic equations.The representative maneuvering flight of pop-up and 180 degrees lever turn are described into mathematical expressions.For a sample current helicopter,the inverse simulation is calculated and analyzed for the maneuvers of pop-up and 180 degrees lever turn.
