FIELD: aircraft industry; marine engineering. ^ SUBSTANCE: invention can be used in devices for displacement of objects, launching of objects, including large size and heavy weight ones from aircraft, ejection, and loading and unloading operations and launching of underwater missiles from launchers of ships. On base of flexible hose placed in folds at definite pitch at regulated and compact manner and fixed with increasing force of step-by-step release in direction of object movement, closed guide with movable bottom and pusher used as propulsive device, chamber is made with step-by-step change of volume providing displacement of object at preset force and speed. Bottom is connected to guide through flanged joint. One end of hose is hermetically connected to cylindrical surface of bottom and other end is hermetically connected with pusher locked on guide to form step-by-step volume change chamber into which gas of corresponding pressure is fed to get required force on pusher to displace object and further combined displacement of object together with connected hose at step-by-step release of folds. At end of displacement, braking of pusher and shockless separation of object from pusher is provided. Object displacement working cycle takes place without unsealing (opening) of variable volume chamber. ^ EFFECT: improved safety and reliability, increased service life of device. ^ 4 cl, 4 dwg |
