概述自40年代第一枚大型火箭运载工具制成,到目前为止,人类进入宇宙空间的活动已经取得了很大进展。阿波罗登月,天空实验室的宇宙考察,对金星、木星、土星的探测等都可说明在火箭运载工具方面所取得的成就,而在运载火箭的研制中,氢氧高能级的出现是运载火箭发展的一个重要标志。目前,氢氧高能级的应用日益广泛成熟。例如上述阿波罗登月任务和天空实验室的发射是由土星Ⅴ运载火箭完成的,而土星Ⅴ运载火箭的S-Ⅱ级及S-Ⅳ B级都是氢氧级;又如,用于探测土星的“先驱者-10号”,就是用宇宙神-半人马座运载火箭发
Overview Since the first large rocket vehicle was launched in the 1940s, much progress has been made towards humankind’s entry into space. Apollo moon landing, the sky laboratory space exploration, the detection of Venus, Jupiter, Saturn, etc. can demonstrate the achievements made in the rocket vehicle, and in the development of launch vehicle, the emergence of high-grade hydrogen and oxygen is to carry An important symbol of the development of the rocket. At present, the application of high-grade hydrogen and oxygen is becoming more and more mature. For example, the above Apollo mission to the moon and the launch of the Skylab were completed by a Saturn V carrier rocket, while the Saturn V carrier rocket S-II and S-IV B were both hydrogen and oxygen; for example, Saturn’s “Pioneer -10”, is the universe God - Centaur rocket launch
