日本科技厅的航空宇宙研究所决定,将利用宇宙开发事业团1993年2月试射的H-2火箭,发射一个大气再入实验回收舱(OR-EX),用以获得回收舱周围温度和分解气体的资料,验证数值计算流体力学(CFD)方法的稳定性;另外,还分析高高度飞行特有的现象。在空天飞机HOPE和空间实验室设计中,需要重要的数值计算流体力学的技术。回收舱发射后,在升至450公里高度圆轨道上时使用反向喷射发动机,从而降轨再入大气层。航宇所在回收舱中装备各种感测器,旨在获取120公里以下的稀薄气体特有的资料,并验证数值计算流体力学方法。目 The Japan Aerospace Science Institute of the Office of Science and Technology has decided to launch an atmospheric re-entry test recovery module (OR-EX) using the H-2 rockets fired by the Space Development Agency in February 1993 to obtain the ambient temperature and Decomposition of gas data to verify the stability of numerical computational fluid dynamics (CFD) method; In addition, the phenomenon of high altitude flight-specific analysis. In space shuttle HOPE and space lab design, important numerical computational fluid dynamics techniques are needed. After the recovery capsule was launched, the reverse jet engine was used when it was raised to a circular orbit at a height of 450 km, so that the orbit reentry into the atmosphere. Aerospace’s recovery capsule is equipped with a variety of sensors designed to obtain information specific to lean gases up to 120 km and to validate numerical computational fluid dynamics methods.
