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...
