title = "Wind effects on the maximum range performance of motor gliders with retractable engine",
abstract = "The effects of constant horizontal wind on the maximum range which motor gliders with a retractable engine can achieve are dealt with. The maximum range flight of this type of ve-hicle, known as saw-tooth mode, 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 engine is retracted. Due to the saw-tooth flight mode, a significant increase of the maximum range is possible when compared with the best steady-state cruise. It is shown that the wind has a considerable influence on the achievable maximum range. Solutions of the periodic optimal flight problem 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 engine.",
