Application of High Temperature Heat-Pipes Leading Structure on the Capsule Type Re-Entry Vehicle

Abstract:

The leading structure of circumferential embedded high temperature heat-pipes in sidewall is considered as thermal protection system to prevent capsule type re-entry vehicle from the serious aerodynamic heating. It can lighten thermal load of windward and make good use of the endothermic capability of low temperature leeward. By means of fluid structure interaction method, we calculate the temperature distribution of capsule under given conditions and the maximum sidewall temperature decreases by 8.45%. The transfer of heat from windward to leeward is achieved, the windward of the thermal load is weakened and the ability of thermal protection is strengthened. The influence of structure parameters of heat-pipe-cooled capsule, flying attributes and materials attributes of coating to thermal protection effect are discussed in this paper to provide some references for the selection of leading structure and materials.
