Modelling and Optimization of Tilt-Rotor Aircraft Flight Trajectories

Tilt-rotor aircraft combine the benefit of helicopter VTOL capability and the flight performance that turboprops possess on range, speed and endurance. Tilt-rotor aircraft have the potential to decrease airport congestion and average flight delay in passenger transportation, while benefits are numerous in i.e. search and rescue, disaster relief and military.Time, money and risk can be significantly reduced through the application of flight trajectory optimization and assessment prior to flight, as this can accurately simulate flight and its related performance limits. A three-dimensional numerical model for a tilt-rotor type aircraft has been derived to fill the gaps that currently exist in tilt-rotor modelling and the understanding of their flight mechanics. After validation, the model is applied to optimize integral flight trajectories in order to assess tilt-rotor flight behaviour in these situations and the differences with ordinary airplanes and helicopters, as the tilt-rotor can exploit its unique rotor tilting capability.
