摘要

摘要: 应用计算流体动力学(CFD)数值模拟方法对DLR-F6模型分别在通流及动力条件下翼/短舱/吊架(W-N-P)组合体部分的气动干扰特性进行研究.结果表明:组合体相互干扰引起的干扰通道附增激波及短舱后部逆压导致的涡流增加了短舱外罩阻力,降低了机翼升力;动力条件较通流条件,F6短舱外罩阻力降低,机翼升阻力特性在零度攻角时有所提高.

Abstract: Based on DLR-F6 model,the wing -nacelle-pylon (W-N-P)configuration dynamic characteristics were calculated by computational fluid dynamics(CFD) method under through flow condition and powered condition respectively.The results show that the interference configuration passage shock wave and nacelle vortex would increase nacelle overall drag and reduce wing lift.The resistance would be lower under power condition compare with that under through flow condition.
