In this hypersonic flight, aerodynamic data and temperature data on TPS (Thermal Protection System) materials and internal structure parts were obtained along its flight trajectory. Surface temperature history of HYFLEX TPS parts were simulated by CFD-FEM (Computational Fluid Dynamics-Finite Element Method) coupling analysis and this type of multi-disciplinary simulation demonstrated its usefulness for high quality evaluation of aerothermal environments of reentry flight. On the present paper, CFD-FEM coupling method is applied to the total thermal structural analysis including internal aluminum structures, such as frames and stringers. This analysis is made to the flight time of 300 sec and good agreements with flight data are obtained for temperature increase of HYFLEX vehicle., 資料番号: AA0001961023, レポート番号: NAL SP-44},
