DEVICE FOR UNLOCKING MOVABLE MEMBER OF SPACECRAFT Russian patent published in 2003 - IPC

FIELD: space engineering; unlocking various movable members of spacecraft. SUBSTANCE: proposed device has body, main and duplicating pyro elements located in said body and spring-loaded by means of pawl having its own axle which is mounted in body for pressing movable member to spacecraft case. Proposed unit is provided with side axles and lever having hole for axle of spring-loaded pawl and for side axle located symmetrically relative to natural axle of pawl which is engageable with shaped slot made in body; first of side axles is articulated with body and second axle is used for connecting the pawl, body and lever engageable with spring-loaded pusher mounted in body. Main pyro element is engageable with first side axle and duplicating pyro element is engageable with second side axle, thus enabling the pawl to turn relative to natural axle without interfering with motion of movable members of spacecraft.
