Comprehensive analysis and estimation system on thermal environment, heat protection and thermal structure of spacecraft

摘要

A comprehensive analysis and estimation system showing the variation history of the thermal physical parameters of spacecraft is presented here. The system consists of four subsystems: numerical simulation and engineering calculation, database, expert prediction and image display subsystems. As an example, the operational results of the subsystems for the model spacecraft are presented. The results provide the pictures and data display of the thermal environment, temperature and thermal stress distribution of the ablation protective layer and the inner structure of the reentry capsule.
