摘　　要：针对软式空中加油对接过程中受油机头波加剧软管锥套飘摆、降低对接成功率的问题,建立了受油机三维模型,利用Delaunay方法自下向上生成非结构网格。通过计算ONERA M6三维翼型表面压力分布和压力系数,验证了三维Navier-Stokes方程和SST k-ω湍流模型的有效性。在此基础上对不同飞行条件下受油机头波进行静态数值计算,分析了头波随马赫数和迎角的变化规律,并通过仿真解释了头波影响下软管锥套的飘摆原因,预测了对接时锥套的运动趋势。In order to solve the problem of increased whipping phenomenon of hose-drogue and reduced rate of success during docking in aerial refueling,the bow wave effect of the receiver was studied. The receiver＇s 3D model was built,and based on the method of Delaunay,the nonstructural grids were generated. Effectiveness of the method and the SST k-ω turbulence model were tested effective by calculating the ONERA M6＇s surface pressure distribution. On the basis of this,the static state numerical calculations of the receiver＇s bow wave effect were conducted. Then the rule of the bow wave effect was analyzed with the change of the Mach and angle of attack. The simulation could explain the whipping phenomenon of hose-drogue under the influence of the bow wave effect,and predict the motion of the drogue during docking.
