| Abstract: | Dynamics analysis on whole engine is significant in engine employment and engine design. A new evaluation method named structural efficiency was put forward to quantify benefit of structures on performance according dynamics. Further, the intensions of structural efficiency were figured and corresponding elementary numerical method was given. The advantages of structural efficiency on whole engine design were pointed through a rotor/supporting structural optimization case. Besides, the research prospects and research emphases were discussed detailedly. |
