 note = {A precise three-dimensional HYFLEX thermal model has been developed. It is intended to be a standard model used in the evaluation of candidate methods making simple re-entry vehicles' FEM models suitable for early design phases. The model consists of about 30,000 elements and includes various types of TPS ranging from carbon/carbon hot structures to ceramic tiles and aluminum structural parts in rather realistic shapes fundamentally using hexahedral elements. On-board equipments such as actuators, propulsion system, parachute, and floating bag are modeled as simple shapes having equivalent thermal capacities. Electronic equipments are neglected because they were placed on instrument panels which were thermally isolated from fuselage by means of insulating rubbers. Aerodynamic heat load for the analysis was obtained fundamentally through CFD calculations not taking account of turbulence transition. Results of an analysis using the model do not show good agreements with flight data of HYFLEX. There are some reasons: (1) the inner radiation heat change within elevon is not included because of the workstation's ability; (2) tentative heat rates are set for areas where CFD did not give; and (3) bolts are neglected in the models of metal fittings of nose cap. These items must be included to improve the model., 資料番号: AA0032819009, レポート番号: NAL SP-53},
