Multibody modelling of rotorcraft dynamics

Some of the more challenging aspects of modelling the mechanical dynamics of rotorcraft systems are addressed in this report. The generic model here presented contains an articulated rigid-bladed rotor and fuselage. Special attention is given to the building of the main rotor model containing flap, lag and feather blade degrees of freedom for each of the equi-spaced blades. A full descriptive AutoSim model is built, simulations results are generated and they are processed for comparison with theoretical findings fi:om the literature and experimental data obtained using VTM code. Such comparisons show that the results are accurate. It is concluded that contemporary multibody analysis tools are applicable with advantage to the modelling of complex mechanical-dynamic systems like helicopters.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
