The validation of helicopter flight mechanics models provides a useful illustration of methods which have broad applicability in terms of establishing the range and accuracy of complex mathematical models. This paper illustrates the use of validation techniques based upon system identification methods and describes benefits which can be obtained from using frequency-domain techniques to eliminate selected sub-systems from the validation process. The problems of validating models used to describe highly nonlinear large amplitude manoeuvres are discussed and the use of inverse simulation for nonlinear investigations of this kind is described. Inverse simulation methods are also considered in the context of model verification - which is taken to mean consistency between a simulation and the underlying mathematical description.
