Description

technical field [0001] The invention relates to the technical field of space flight, and is particularly suitable for a technology for safe flight of a space vehicle in a high-vacuum microgravity environment without being discovered by various detection systems, specifically a space stealth flight technology method. Background technique [0002] At present, space detection mainly includes radar detection, visible light detection, laser detection, infrared detection, sound wave detection and other reconnaissance and detection technologies, which are used to detect and discover space flying objects. The detection method realizes the stealth and safe flight of the aircraft, and is not discovered by various detection techniques. In the world, anti-radar detection technology is relatively mature, but other detection methods cannot be effectively applied to space vehicles due to various factors such as application occasions and application conditions, making it difficult for aircr...

AI Technical Summary

Problems solved by technology

[0003] However, it is not easy to use the space cold shielding system of cryogen phase change refrigeration to realize the infrared stealth of the aircraft. Because the aircraft has complex aerodynamic heat transfer conditions during the start-up and stable flight process, the low-temperature fluid in the cold shield is in a fierce phase. Variable and multi-phase flow state accompanied by drastic changes in pressure and temperature, a large amount of saturated steam and superheated steam are continuously produced, and the wet steam and superheated steam are continuously discharged during the process of variable pressure and temperature, causing space flight disturbances, Vibration problems, sudden pressure rise problems, refrigerant solidification problems, uneven surface temperature distribution problems, vapor-liquid two-phase flow problems, space complex heat transfer problems, aerodynamic friction heat transfer problems, overheating and supercooling problems, filling anti-frost problems, etc. and other complex issues
