| 摘 要： | GE90-115B发动机是目前世界上推力最大的发动机,由GE90-94B发动机衍生发展而来.与传统的衍生发展不同,GE90-115B发动机的高压压气机减少1级,风扇转子支承作了重大改变,将1号滚珠轴承改为直径特大的滚棒轴承,滚珠轴承则置于风扇轴后端处.对风扇转子支承方式的变化作了深入分析,同时对风扇、高压压气机、低压涡轮、轴承等的结构设计改进进行了分析,可供航空发动机结构设计人员参考.

| Abstract: | 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 |
