宇宙开发事业团从1981年开始研制H-1火箭,这是日本未来的运载火箭。它的第二级采用10吨推力(真空)的液氧和液氢泵压推进系统,该推进系统有一燃气发生器循环的发动机(LE-5)。1977年以来,宇宙开发事业团和航空宇宙技术研究所已经在研制LOX和LH_2涡轮泵系统(双轴串联涡轮)。在1980年成功地完成了涡轮泵系统的全功率闭式回路试验。本文将介绍涡轮泵系统研制方面的进展。
The Cosmological Development Agency has been developing the H-1 rocket since 1981, which is the future launch vehicle for Japan. Its second stage features a 10 ton thrust (vacuum) liquid oxygen and liquid hydrogen pumping propulsion system with a gas generator cycle engine (LE-5). Since 1977, the Space Development Corps and the Aerospace Technology Institute have been developing LOX and LH_2 turbo-pump systems (twin-shaft tandem turbines). In 1980, the full-power closed loop test of the turbo-pump system was successfully completed. This article will introduce the development of turbo pump system.
