Problems solved by technology

However, there are many variables in the design of thermal protection structures, including many typical structural dimensions, material performance parameters, etc., and the constraints are complex, including heat protection, heat insulation, strength, modal, etc.

In the traditional thermal protection system design method, there is no way to consider many factors, the design result margin is too large, the design result is too conservative, and it is difficult to directly achieve the optimal design

Moreover, the design efficiency of traditional methods is low, and in some cases, human error is prone to occur, resulting in design risks
