Abstract: Aeroshape design is one of the key technologies for Winged Re-entry Vehicles (RV-W). The influence of aerodynamic parameters on re-entry flight performance is analysed, and the criteria for aerodynamic shape design of winged re-entry vehicles are discussed. Based on the design criteria, the X-37B analog is employed to optimize the flight's aerodynamic performance. The parametric geometry modeling method, along with the aerodynamic/aerothermodynamic fast prediction method, are integrated into the aeroshape optimization. The light-weight Thermal Protection System (TPS) is designed and optimized for optimal configuration. Results indicate that the aerodynamic characteristics of the optimal configuration are greatly improved compared with the initial configuration, and the TPS weight fraction (8.7%) is less than the statistical data of similar aerospace vehicles. The aeroshape integrated design optimization method for RV-W could provide reference for similar vehicle designs.
