SIMULATION AND CONTROL OF DEFORMABLE AEROSPACE MECHANISMS

The paper illustrates the real-time simulation capabilities of general-purpose multibody analysis applied to the challenging problem of rotorcraft dynamics, where the need to use small sample rates to capture the dynamics related to the rotation of the rotor conflicts with the need for small worst-case computational time for each time step. The simulation system is entirely based on free software, most of which developed at the Dipartimento di Ingegneria Aerospaziale of the University “Politecnico di Milano”. Relevant performances resulting from its application to the analysis of different rotorcraft models are presented.
