MICROSTRUCTURAL SPACECRAFT THERMAL CONTROL SYSTEM Russian patent published in 2012 - IPC B64G1/50 

FIELD: transport.

SUBSTANCE: invention relates to cosmonautics and concerns devices for heat transmission measurement, namely - microstructural systems containing resilient flexible deformable actuating elements. Microstructural system for spacecraft (SC) thermal control and moving contains substrate screens. The substrate is fixed on SC surface or on its component. The screens begin to move under thermal flow action. Moving screens are orderly located over substrate, made as matrix with resilient-articulated cantilevers consisting of parallel trapezoidal inserts of single-crystalline silicon with orientation [100] and connected by polyimid inlays formed by polyimid film. The screens are fixed on mounting elements on the substrate or on immovable frame rigidly fixed on mounting elements of the substrate. When heated or cooled the screens simultaneously change their spatial position by starting their up or down movement under action of strong strain of materials.

EFFECT: creation of effective microstructural SC thermal control system operating in wide temperature range (temperature of liquid nitrogen); higher manufacturability of product and its reliability characteristics, tolerance to cyclic loads due to use of screens deformed under temperature action without electronic control circuit.
