Abstract: A load glider has, between the parachute surface and the load, a device in which a reversible transfer of mechanical energy from the main lines to the steering lines takes place, so that essentially only frictional forces are to be overcome during the operation of the steering lines. The device includes two differential gears, which are arranged in parallel and are accommodated in housings in which a steering line is wound up on a roller with a larger diameter and a main line is wound up on the other roller with a small diameter. Gears, which can be driven by pinions driven by electric motors, are flanged onto the larger rollers.
