S1904-2-5 有人宇宙船の緩降下、着陸技術(大気突入・減速技術(2),社会変革を技術で廻す機械工学)

抄録

Following the two big projects, International Space Station and Space Shuttle, new projects are under consideration in many national agencies, especially in NASA, ESA, and JAXA. NASA has been developing ORION in Constellation program, but the new president, Obama changed the original planning. ESA is also considering a new project, and JAXA is discussing strategy of national space development. In any projects under discussion which go to space and return, the reentry should be one of the most important technology, and decelerating decent velocity and eliminate strong impact at landing for crew safety. This paper shows the in-house study for acquiring the method for getting landing impact. The exact simulation of the landing impact is important for realizing the Japanese return space vehicle.
