Comparisons have been made of the behaviour of a rigid blade rotor simulation model with data gathered on a Puma helicopter during quick-hop manoeuvres as part of a validation study. Two validation techniques are investigated; the first method involves driving a full helicopter simulation model with pilot controls, whilst the second involves driving an isolated rotor model with rotor controls and fuselage motions. Relative merits of each method are discussed and, in the ·case of the quick-hop manoeuvre, the advantages of using the latter method, called open loop simulation, are demonstrated. Inflow dynamics and nonlinear section aerodynamics are briefly discussed and preliminary results illustrating the effects of these modelling features presented. It is concluded that the method of driving open loop simulation is ideal for validating and understanding rotor behaviour and will be investigated for a broader range of flight conditions and rotor system types.
