Abstract

The range of a powered sailplane employing a retractable propeller-engine combination is maximized. The maximum range trajectory is of periodic nature because there are alternating flight segments in terms of the best operating condition of the powered phase as opposed to that with zero thrust where the propeller-engine combination is retracted. It is shown that a significant enlargement of the maximum range can be achieved when compared with the best steady-state cruise. Solutions of the periodic optimal flight poblem are constructed, using an efficient optimization method and a realistic mathematical model for describing the motion of the vehicle as well as the procedure for extending and retracting the propeller-engine combination.
