ABSTRACT:
In a motor-glider provided with a propeller power system fully encased within the fuselage thereof, outer shapes of the elements adapted for selectively closing air-intakes and, when required, an outlet are designed quite flush with the streamlined shapes of the surrounding portions of the motor-glider and the air is ejected in directions away from the tail boom, whereby aero-dynamic drag acting on the motor-glider during power-off gliding is considerably minimized.
