| Abstract: | 3-D models of the rotor system of a micro-gas turbine engine were built by using the commercial software Catia. The Stress of the rotational parts were analyzed basing on finite element method,and the participation of stress at the max power condition was obtained. Modal frequencies and shapes were obtained through modal analysis of the rotor system. The results will be the theoretical evidence to guarantee the engine running safely. |
