FIELD: aircraft industry; marine. ^ SUBSTANCE: invention can be used in devices for displacement and bringing objects of different overall dimensions and masses out of different overall dimensions and masses out of aircraft, ejection, loading and unloading works, and launching of underwater missiles from marine launchers. On base of flexible hose arranged in regulated and compact manner, closed guide with bottom and pusher used as propulsor, variable-volume chamber is formed providing displacement of object at preset force and speed. Hose is laid in folds fixed with increasing effort of step-by-step release in direction opposite to direction of movement of object. Hose is hermetically connected to guide in bottom area and to pusher locked on guide, and bottom connected with pressure source, is hermetically connected with guide forming chamber of step-by-step change of volume into which gas is supplied under pressure. Pusher, when being moved, released, step-by-step, folds of hose starting from fold nearest to pusher. Remaining part of hose does not move at increase of volume of chamber. Working cycle is carried out without unsealing of variable-volume chamber. Containers with nozzles to deliver combustion products of solid propellant generators under pressure exceeding gas pressure in chamber into cooler chamber are installed on bottom from outside. Nozzles are orientated in direction of movement of object having narrow diagram of direction of cooler agent atomizing. ^ EFFECT: improved reliability and safety, increased service life of device. ^ 9 cl, 4 dwg |
