Problems solved by technology

However, at present, most of the existing test methods use calculation methods such as computational fluid dynamics to carry out numerical simulations in the early stage, and the simulation results tend to be idealized. It is difficult to accurately describe the specific changes of various parameters in complex and extreme environments under the influence of multiple physical fields. The requirements for each parameter information are too stringent and difficult to reproduce in the real scene; however, in the real scene test environment, there are a large number of environmental interference factors, which greatly affect the accuracy of the test results, and will consume huge manpower and material costs. This reduces research efficiency to a certain extent, limits the detection of multi-parameter information in extreme environments under the joint action of multiple physical fields such as the surface of hypersonic aircraft, and restricts the development of thermal protection technology for the surface of hypersonic aircraft
