摘　　要：以亚声速、大展弦比飞机机翼挂装大型吊舱为研究对象,通过建立机翼和吊舱的CFD计算模型,侧重于吊舱气动特性计算,对挂装吊舱时机翼连接处缝隙、吊舱形状及舵面偏转等因素对吊舱的影响进行分析。计算结果表明,连接缝隙和舵面偏转对吊舱的气动力影响相对明显,但由于飞机外挂布置是由很多因素共同决定的,本计算结果可为不同专业选型提供设计参考,以期得出更加合理的挂装方案。The object of the research is large-scale nacelle installed on the wing of subsonic aircraft with high aspect ratio.Through establishing CFD computation model of wing and nacelle and focused on aerodynamic characteristics computation,the influence of connecting gap,shape of nacelle and control surface deflection on the nacelle installed are analyzed.The computational results show that there is an apparent influence of connecting gap and surface deflection on aerodynamics of the nacelle.As the store installation arrangement is effected by many factors,the computational result can be provided as design reference for different specialties to obtain more reasonable installation scheme.
