Abstract EN
The metallic thermal protection system (MPTS) is a key technology for reducing the cost of reusable launch vehicles, offering the combination of increased durability and competitive weights when compared with other systems.
A two-stage optimization strategy is proposed in this paper to improve thermal and mechanical performance of MTPS while minimizing its weight.
Sensitivity analysis is conducted to determine the influence of various design variables, and these variables are classified into two groups according to the results.
Three main parameters are optimized in the first-stage optimization, and others are optimized in the second stage.
Combining the response surface method with genetic algorithm ensures the computational efficiency of this strategy.
Optimum results show that the thermal insulation capability of MTPS is improved by 20% with little mass cost, validating the feasibility of this optimization strategy.
