thrust to weight meaning in English

推力

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
本文提出采用自适应遗传算法( adaptivegeneticalgorithm )和有限元方法( finiteelementmethod , fem )结合即aga - fem方法进行纤维增强型复合材料层合壳结构的优化设计，并对某航空发动机复合材料机匣进行优化设计分析，取得了很好的效果。
