China’s next-generation manned spacecraft need to take into account both near earth and lunar exploration missions, so it is required that the reentry capsule has the ability to re-enter and return at the second cosmic speed. To meet the second cosmic velocity reentry and return as the main goal, aerodynamic shape optimization design of the next-generation manned spacecraft reentry capsule is carried out. Firstly, the requirements of the reentry capsule of the new generation manned spacecraft are sorted out, and the preliminary shape selection analysis of the reentry capsule is carried out. Secondly, an approximate model is established based on the results of engineering calculation and CFD software numerical simulation, and the aerodynamic shape of the reentry capsule is optimized by multi-objective optimization method. Finally, the effective verification of aerodynamic shape is completed through flight test.
