宇宙开发事业团在仿制美国雷神-德尔它运载火箭的基础上研制成了N系列运载火箭,之后,为了进一步满足本国卫星用户对大容量重型卫星的需要,又在积极从事性能好、运载能力大、制导精度高、工作可靠的H-1运载火箭的研制工作。H-1运载火箭的研制原则有两条:一条是尽量利用N系列火箭现成的部件与技术(其中有些是从雷神-德尔它火箭那里延续下来的),另一条是新研制象低温推进和惯性制导这样先进的宇航系统。本文扼要介绍H-1火箭的研制计划,总体结构,设计参数与工作能力,同时还要介绍诸如低温液氢-液氧发动机、低温贮箱、第三级固体推进剂火箭发动机以及惯性制导装置等主要系统的研制现状。
In order to further meet the needs of its satellite users for large-capacity heavy-duty satellites, the Space Development Corps has developed an N-series carrier rocket based on the imitation of the US Thor-Del carrier rocket. It has also actively engaged in large-capacity and large-capacity , Guidance accuracy, reliable work of H-1 launch vehicle research and development work. H-1 launch vehicle developed two principles: one is to make full use of N-series rocket ready-made components and technologies (some of which are from the Raytheon - Del Rockets rocket where there continued), the other is the development of new low-temperature propulsion and inertia Guidance of such advanced aerospace systems. This paper outlines the H-1 rocket development plan, overall structure, design parameters and capabilities, but also introduces such as low temperature liquid hydrogen - liquid oxygen engine, cryogenic tank, third solid propellant rocket engine and inertial guidance device Development of major systems.
