THERMAL COTTER-PIN FOR COUPLING AND UNCOUPLING SPACESHIP STRUCTURAL MOVING ELEMENTS Russian patent published in 2012 - IPC B64G1/64 

FIELD: transport.

SUBSTANCE: invention relates to space engineering. Proposed device comprises case, drive main and redundant elements electrically connected with spaceship control system, and working rod. Said drive elements are made from material with shape memory and composed of closed-loop conductors covering insulating rollers. One of the latter is fitted on working rod axle while another is arranged on structural bracket rigidly secured in case. Sleeve interacts with working rod axle while yoke interacts with that of structural bracket. Note here that both sleeve and yoke are spring-loaded. Proposed device is equipped with power supply module to ensure required parameters of current supplied to drive elements via electric contacts arranged at centers of said conductors, and contact transducers mounted on brackets rigidly secured on both sides of said case. Leaf springs are secured at said brackets to interact with sleeve conical ledges and contact transducers in operation of cotter-pin.

EFFECT: higher reliability.
