Initial pressure inside the tube was 0.86 MPa, whereas pressure inside the vacuum chamber was 400 Pa, and fill fraction between 19.8 % and 100 % were studied. The Impactor calibration and the error evaluation was carried out. The specific impulse increased most when length of the extension tube is 1.22 m (longest case) and we think that lower specific heat ratio driver gas or a longer extension tube can produce higher specific impulse., 形態: カラー図版あり, 資料番号: AA0064292054}, publisher = {宇宙航空研究開発機構宇宙科学研究本部, Institute of Space and Astronautical Science, Japan Aerospace Exploration Agency (JAXA)}, title = {衝撃波管にて生成される力積に関する研究}, volume = {平成20年度}, year = {2009} }
