Inverse simulation is used to calculate the control displacements required for a modeled vehicle to perform a particular maneuver. As with all simulations, the usefulness of the technique depends on the validity of the mathematical model used. To incorporate the latest forms of helicopter model (individual blade models) in an inverse framework, it has been necessary to modify existing inverse techniques. Such a model is described in this paper along with an inverse algorithm capable of accommodating it, The resulting simulation is validated against flight data and comparisons are made with a more basic model. It is shown that the basic disk model compares well with the more comprehensive individual blade model until the severity of the maneuver is increased to encompass flight states where nonlinear aerodynamics effects are prevalent.
