摘　　要：硬式空中加油杆是空中加油的关键部件。借助于商业CFD软件FLUENT,对某型硬式空中加油杆在不同攻角、不同飞行马赫数的气动力进行了计算,得出了该型加油杆升力系数、阻力系数以及随飞行马赫数和攻角的变化规律。仿真结果表明,计算的气动参数可以为硬式空中加油杆的模型和数据提供依据和参考,与传统计算方法相比有一定的优越性。Flying boom is the key component of the boom aerial refueling. By using the CFD software FLUENT, a certain flying boom is computed in different Mach number and different attack angles. Regarding this type of flying boom, the lift coefficient, drag coefficient, as well as the Mach number, and the variation of attack angle are obtained. The results indicate that the computation result can provide basis and reference for model and data of the flying boom. It has certain advantages than traditional computation methods.
