Optimization and Re-Design of Integrated Thermal Protection Systems Considering Thermo-Mechanical Performance

Integrated thermal protection system (ITPS) is regarded as one of the most promising concepts with both insulation and load-bearing capacities. However, traditional layout webs could inevitably lead to short effects high risk buckling failure ITPS. A topological optimization method for unit cell ITPS was established minimize equivalent conductivity elastic strain energy constraint maintaining structural efficiency. The re-designed consulting optimized configuration. In order control buckling-mode shape associated load ITPS, new design further optimized, subjected total weight initial design. Detailed finite element models were validate responses. By contrast, presents lower bottom surface temperature better characteristics, performing a balance between constraints.
