Description This paper describes work done in optimizing the transition manoeuvres between vertical and horizontal flight for a tail-sitter unmanned air vehicle. This work is part of an ongoing research program involving the construction and test of a concept demonstrator tail-sitter UAV, the “T-Wing, ” that is being undertaken by the University of Sydney in collaboration with Sonacom Pty Ltd. The use of an unmanned air-vehicle (UAV) with a vertical take-off and landing (VTOL) capability that can still enjoy efficient horizontal flight promises significant operational advantages over other vehicles. However, the transition between these phases of flight is one problem that needs to be addressed to make the vehicle effective. This paper looks at using numerical optimization techniques coupled with a 6-DOF non-linear model of the vehicle to obtain the best possible transition maneuvers in terms of minimizing such things as the time to complete the transition and any excess height gain during the maneuver as well as avoiding unpredictable regions of the flight envelope.
