THERMOMECHANICAL SYSTEM FOR ENSURING THE THERMAL REGIME OF THE SPACECRAFT Russian patent published in 2022 - IPC B64G1/50 

FIELD: space technology.

SUBSTANCE: invention relates to the means of thermoregulation of spacecraft. The proposed system contains flat screens (2) installed above the protected surface (1) by means of thermal micromechanical actuators (MMA) (3), which on one side are fixed on the surface (1) perpendicular or at an angle to it, and on the other side, parallel or at an angle to the surface of the screen (2). Each MMA (3) consists of a set of silicon beams (not shown) united by a bearing layer of polyimide forming hinge nodes at the joints of the beams. With high heat release from the back of the surface (1), the temperature of the screens (2) and MMA (3) increases, polyimide expands, straightening the MMA structure and opening the screens. This increases the heat discharge from the surface (1).

EFFECT: decrease in the electrical power required to compensate for heat loss from the spacecraft body, as well as an expansion of the range of heat exchange problems solved by the system.
