Description

technical field [0001] The invention relates to the technical field of multi-field coupling ground simulation testing, in particular to a heat-force-oxygen-laser multi-field coupling ground simulation testing system and method for thermal protection materials. Background technique [0002] Hypersonic aircraft refers to aircraft with a flight speed greater than Mach 5. In recent years, hypersonic aircraft in some countries have successfully tested and become a potential threat in aerospace offensive and defensive confrontation. The emergence of hypersonic vehicles has greatly improved the early warning capabilities of defense systems, the difficulty of precise target detection, the maneuvering overload against interception, and the requirements for high-precision guidance and control of interceptors, posing great challenges to traditional air defense systems. Due to its rapid response, fast firepower transfer, high interception rate, and flexible configuration, high-energy la...

Problems solved by technology

[0004] At present, there is no simulation system in the prior art that can simultaneously load multiple loads of heat (temperature field), force (force field), oxygen (environmental field), and laser (laser field), and independently adjust and control each load , which involves high temperature loading, stress loading, laser transmission, and the interference and contradiction of many physical fields such as vacuum, sealing, and insulation. Conventional testing devices are difficult to meet the requirements.
