  1. To optimize specific impulse to 700s or 800s, the thrust - weight ratio could be improved to 1. 23 or 1. 41, it is enough to achieve the launch requirement for this vehicle

    進一步將比沖優化至700s或800s ,可以將推重比提高至1 . 23或1 . 41 ,這樣就完全能夠保證發射任務的完成。
  2. Compress disk is the very important rotational component in the areoengine. when the compress disk is working, the grads of temperature and stress between the rim and the center of the disk are great. in order to raise the thrust - weight ratio of the disk and reduce oil consumption. the best prospective way is the dual alloys disk used

    壓氣機盤是航空發動機上一個很重要的轉動部件,壓氣機盤工作時,輪緣和輪轂溫度梯度和應力梯度較大,為了提高飛機發動機推重比、減低耗油量,要求壓氣機盤的工作溫度、使用性能更高,雙合金盤製造是最有發展前景的技術。
  3. Weight to thrust ratio

    重量推力比
  4. Composite laminate shells have been applied more and more widely in aerospace structures. in order to increase thrust to weight ratio and improve the comprehensive performance of airplane, optimization design must be carried out. this thesis brings forward utilizing the method of aga - fem, which combines adaptive genetic algorithm ( aga ) and finite element method ( fem ), to optimize fibre - reinforced composite shells

    本文提出採用自適應遺傳演算法( adaptivegeneticalgorithm )和有限元方法( finiteelementmethod , fem )結合即aga - fem方法進行纖維增強型復合材料層合殼結構的優化設計,並對某航空發動機復合材料機匣進行優化設計分析,取得了很好的效果。
