中国航天进展

The Progress of China's Astronautics

中国从50年代末期开始航天技术的基础研究工作,30年来,已成功地研制了长征系列运载火箭和多种卫星,包括科学探测和技术试验卫星、通信广播卫星和空间物理探测卫星等,取得了重要成就。这些航天系统都是中国自行研制的,可靠性高,费用较低。 本文详细介绍了中国在8个航天专业技术领域的研制水平,从卫星姿态控制、火箭发动机到卫星返回技术和环境模拟试验设备,这些先进技术为有效地开展航天技术的国际合作提供了可能性。 最后,本文对人类未来的航天活动发表了一些建设性的意见。

China's space activities began at the end of 1950's. Since then, for about 30 years, she has successfully developed Long March family of launch vehicles and various kinds of satellites, including scientific exploratory technological experimental satellite, communication & broadcasting satellite (STW), and the satellite of space physical exploration (SJ-2). All of these systems are of high-reliability, low-cost and made natively.This paper presented China's state of arts in 8 main space technology arears in detail, ranging from satellite attitude control and rocket engine to satellite recovery technology and environmental test equipment. With wide spectrum of these specific space technologies, China provides a great potential for international cooperation in space.Finally, this paper put forward some constructive opinions on the future space activities of mankind.
