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, loading and unloading operations and launching of underwater missiles from launchers of ships. On base of flexible hose placed in folds at regulated and compact manner, closed guide with bottom and pusher used as propulsive device, variable volume chamber is made providing displacement of objects at preset force and speed. Hose is placed in folds at definite pitch and is fixed with increasing force of step-by-step release in direction of object movement. 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 step-by-step volume change chamber into which gas 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. Bottom is furnished with valve for emergency pressure discharge into atmosphere through discharge main line. At end of displacement, braking of pusher and shockless separation of object from pusher is provided. Chamber is opened only after separation of object. Pressure discharge from chamber is effected through limit switch controlled valve. ^ EFFECT: improved safety and reliability, increased service life of device. ^ 7 cl, 5 dwg |
