英文摘要:

      US aerospace development strategies were analyzed from 1950s, and the development of US aerospace was introduced and the development and the features of four aerospace platforms such as aviation platform, approach space platform, access space platform and space technology platform were concluded. The status and future development of propulsion system technologies including adaptive engine, high speed turbine engine, scramjet, and turbine based combined cycle engine and rocket based combined cycle engine required for four platforms were overviewed. The important enlightenments of implementing national strategy, grasping technology foundation and adjusting target were obtained for aerospace development in China
