发动机短舱对翼身组合体跨音速气动特性影响研究

为了达到增升减阻的目的，现代民用飞机设计越来越重视飞机各个部件之间的相互影响。部件之间的气动干扰影响着飞机的气动特性，合理的气动布局可以产生有利的气动干扰，获得满意的气动特性。针对民用飞机超临界机翼——翼吊式发动机短舱气动布局，通过数值模拟方法，研究了跨音速飞行时，发动机短舱对整机的气动特性影响。

Research on Transonic Aerodynamic Performance Impact of the Engine Nacelle

To achieve the purpose of raise the left and reduce the drag, the design of modern civil aircraft more and more concerns the impact between the various components of the aircraft. Aerodynamic interferences among components have considerable impact on the aerodynamic characteristics of complete aircraft. Favorable interferences which lead to satisfactory aerodynamic characteristics can be resulted from careful design integration of reasonable aerodynamic configu- ration. In this paper, the research which is based on CFD is presented on the impact of the aerodynamic interferences of wing - hanged nacelles to a supercritical wing during transonic flight.
