| 摘 要： | 民用客机主要针对巡航外形设计,这就需要通过静气动弹性修正得到型架外形,保证型架外形在设计巡航状态飞行时,气动性能能够恢复到巡航设计状态。本文基于混合网格的N-S方程和结构柔度矩阵方法的耦合求解,发展了大飞机静气动弹性计算方法。根据静气动弹性变形过程的可逆性,结合飞行器质量分布、发动机推力以及巡航飞行重量等设计参数,发展了考虑静气动弹性效应的飞机型架外形修正方法。利用所发展的修正方法,获得了某大型客机巡航飞行的型架修正外形,同时分析了其它飞行工况的弹性气动特性,并通过算例比较验证了本文发展方法的有效性。

| Abstract: | The design of civil airliner is mainly to the shape design of the airliner in cruise state,so jig shape should be obtained by the correcting method of aeroelasticity,to ensure the aerodynamic performance of the airliner when it is flying in cruise.In this paper,a static aeroelasticity analysis method is developed by the coupling solving hybrid grid-based N-S equation and structural flexible matrix method.Based on the linear structural reversibility and considering the mass distribution,engine thrust and wei... |
