| 摘 要： | 空中加油是提高飞机航程、活动半径的重要方法。通过对四种固定受油管的数值模拟,从流动特性的改进方面说明了合适的截面及倾角会降低受油管绕流的压力脉动,进而使噪声降低。

| Abstract: | Air refueling is an effective method to increase the cruise range and active radius of a fighter. Four configurations of refueling tubes with different section and inclination have been simulated by CFD. Computation result shows that there is no separated flow over the tube with airfoil section and coherent pressure fluctuation in wake flow is reduced. Obviously this is very significant for reducing noise in the cabin of a fighter. |
