Abstract

This invention relates to a self-pressurization type space low-infrared radiation cold-shield system device applied to an implementation of a space anti-infrared detection invisible aviation technology, which is an indispensable technology for space penetration attack under the condition of the modern high technology warfare. A low-temperature refrigerant carried by the system is pressurized by the method of self-pressurization during the space mid-course aviation process, and is throttled and refrigerated twice to implement the cold shield effect on a spacecraft, and to reduce intensity of infrared radiation of the surface of the system; or internal high temperature parts of the system in the air-operated friction course are cooled by a self-pressurization temperature control device during the starting and accelerating process to achieve the aim of space anti-infrared detection invisible aviation, and to enhance capability of space infrared visibility and penetration of the aircraft and finally to meet the demand on penetration of the space defence system of the opponent. The invention can reduce the intensity of the infrared radiation of the surface of the system and effectively improve the penetration capability of aircrafts by use of different refrigeration methods and different penetration technologies according to the demand on the practical air defence technology.
