摘要
把镜像涡理论用于计算机翼与机身、机翼与外挂物的气动干扰，并开发了复杂全机带多个外挂物的面元生成程序。通过对４种外形的计算并与实验对比表明，本方法大大提高了面元法计算精度，拓宽了使用范围，减少了人为因素对计算结果的影响。在复杂外形的气动布局设计和气动特性预估中，发挥了积极的作用。
The paper successfuly applied the mirror vortex concept based on slender body theory to the computation of interference aerodynamics between wings and fuselage or wings and external stores of an airframe,and developed program to generate the correspondent panel geometry of a complex configuration with multi external stores.Comparison of computation with experiment of four types of configurations show that the procedure greatly improved the accuracy and extended the application of panel method,and reduced the effect of manual input in the panel method.This procedure has played an active role in aerodynamic configuration design and characteristics calculation for aircraft B,C,D.
