Abstract

The contemporary approach to helicopter mathematical modelling in simulation for handling qualities applications, is to represent each blade individually. This allows incorporation of effects not possible with a multiblade disc representation of the rotor system. This Paper addresses the validation of such a model, which is uniquely performed for large amplitude manoeuvres, using a recently-developed approach to inverse simulation. The method is reviewed in the context of model validation, and comparisons between simulation and actual data are presented for a Puma helicopter executing sidestep manoeuvres in low-speed flight. The focus for interpreting the results is in the area of wake modelling. It is concluded that further developments are necessary in this area if helicopter flight mechanics models are to be used in simulation of role-related flight.
