UNIT SEPARATION MECHANISM Russian patent published in 2008 - IPC B64G1/64 

FIELD: transport.

SUBSTANCE: invention refers to space engineering and may be used for separation of essentially on-board plug-type connections connecting airborne vehicle with launching site. Mechanism contains on-board and detachable boards held by lock installed at detachable board side in hermetic cavity in that board. Lock includes collet and rod with bar hold made with ability to fix blades of collet by its ends, and also ball-end link. Mechanism is also supplied with support cartridge, sleeve, piston, spring, and stop. One ball-end link is placed in slot made in rod with bar hold interacting with sealing element installed at bottom of support cartridge. Support cartridge is secured on detachable board in said hermetic cavity. Sleeve is installed on support cartridge and it has lid. Piston is hollow, it is placed inside sleeve and it may slide inside. Inside piston there is spring interacting with inner surface and sleeve bottom. Stop is installed in through orifice made in sleeve side wall, it is supplied with fixing arm and contacts with outer surface of piston bottom. Other end of link has spherical support element interacting with piston bottom outer surface. Link has adjustable axial position. Piston bottom has through orifices. Distance between outer surface of piston bottom and sleeve lid is greater than fixing clearance of blades of collet by rod's end. Spring power is greater than collet clamp unlocking effort.

EFFECT: improvement of reliability of unit separation in operation.
