II.1.9 構造の立場から見たSSRロケットの性能向上の可能性について(1 機体および構造)(II.関連研究) Rossibility of Structural Improvement of SSR-Rocket 池田, 健 富田, 文治 古田, 敏康 酒巻, 正守 IKEDA, Ken TOMITA, Bunji FURUTA, Toshiyasu SAKAMAKI, Masamori The small test rocket SSR, Which reached the altitude 25.8km in the latest flying test, is still possible to be improved from the structural point of view. From the results of the ground tests, the weight of some structual parts can be reduced and the reducible total weight is estimated about 30% of the total structural weight. It is shown that this weight reduction is also possible from the aeroelastic point of view. By this improvment, the increase of the maximum attainable altitude of SSR will be about 4. 7 km. Furthermore, this result is compared with the effects of aerodynamical improvement and of the improvement of the propellant. 資料番号: SA0124881000 東京大学宇宙航空研究所 1966-06 jpn departmental bulletin paper https://jaxa.repo.nii.ac.jp/records/31826 0563-8100 AN00161914 東京大学宇宙航空研究所報告 2 2_B 622 626 https://jaxa.repo.nii.ac.jp/record/31826/files/SA0124881.pdf application/pdf 278.2 kB 2020-01-24
