DEVICE FOR DEPLOYMENT OF ULTRA-RED TARGET IN SPACE Russian patent published in 2008 - IPC B64G1/22 B64G1/64 F41J9/08 

FIELD: rocketry and space engineering; mounting the device on spacecraft external surface and subsequent separation of ultra-red target in form of inflatable thin-film envelopes with dark coat.

SUBSTANCE: proposed device has cassette with inflatable envelopes and doors, nitrogen generators with pyro retarders, starting device with spring mechanism for ejection of cassette from starting device and electric connector. Door axles are provided with torsion springs. Nitrogen generators provided with check valves are located on one side from thin-film envelopes. Height of ejection mechanism in compressed state is comparable with diameter of each nitrogen generator. Electric cable of electric connector has free loop whose length is equal to path of motion of cassette till moment of steady ignition of pyro retarders. Circuit supplying the electric pulse to igniter of each pyro retarder is provided with terminal closing this circuit at the beginning of motion of cassette.

EFFECT: reduced overall dimensions of device; enhanced reliability; simplified construction.
