Spacing stealth flight process

Abstract

A space stealth flight technical method comprises an infrared stealth technology, an antiradar stealth technology, an anti-visible light stealth technology, and an anti-laser detection technology. The infrared stealth technology adopts a space cold shielding system near triple point refrigeration technology mainly comprising a ground filling up process, a ground pressure filling up process, a starting process and a steady-state flight process, each process is implemented by a layered liquid storage method, a saturated vapor outlet pipe diffusion diversion method, a cold vapor emission control method and a superheated vapor secondary diffusion diversion method. The inventive method integrally utilizes the anti-infrared, anti-radar, anti-visible light, anti-laser detection technologies and other technologies of space aircrafts, and enhances the full-dimensional space stealth flight ability of the aircrafts, so as to meet the space safety flight requirements; and is especially suitable for the safety stealth flight of the space aircrafts.

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
