摘要
21世纪先进航空发动机的动力传输系统将采用无接触的磁力轴承取代传统的滚动轴承,在高速转子上安装电起动机/发电机,用全电气化传动附件代替机械传动附件,使发动机的推重比、工作寿命及可靠性获得显著提高。
The power transmission systems of advanced aeroengines for 21 century shall use the noncontact magnetic bearing in place of the traditional rolling ones. Electric starter/generators shall be installed on the high-speed rotors,and electrified accessories be substituted for machanical one,that lead to a great improvement of thrust/weight ration, service life and reliability.
