METHOD OF PRODUCING SPACESHIP THERMAL CONTROL SYSTEM AND DEVICE TO THIS END Russian patent published in 2011 - IPC B64G1/50 

FIELD: transport.

SUBSTANCE: invention relates to methods of devices of spaceship thermal control. Proposed method and device proceeds from exploiting the difference in coefficients of linear thermal expansion of spaceship body 1 (from aluminium alloy) and metal rod 3 (for example, from invar alloy). Spaceship is provided with driven shutter flaps 6 with heat isolation 2. Flaps drive comprises drums 8 fitted on flap axles 7 whereon thread 9 is wound, rod 3 secured on body 1 and converter 5. The latter has its one end coupled with said thread 9 and its opposite end coupled with rod 3. It serves to convert linear difference in coefficients of thermal expansion of spaceship body 1 and metal rod 3 into tensioning or loosening of thread 9 during rotation of drum 8 in opening or closing flaps 6. Device 5 may made up of pulley block suspended to bracket 4, or of a system of bell cranks.

EFFECT: simple and reliable system, power saving and reduced weight.
