摘要

摘要: 以配装大涵道比涡扇发动机的某型运输机在未铺装跑道静止开车、滑行等实战使用环境为背景，建立了全尺寸三维仿真计算模型，通过数值仿真，分析研究了风速、风向以及滑跑速度对该型飞机进气道地面涡的流动特性及发动机进口畸变特性的影响。结果表明：该型运输机270°侧风条件下，随着风速的增加，地面涡强度呈现先增加后减小的规律，风速为2~4 m/s时强度最大，风速在6 m/s以上地面涡特性消失；风速为3m/s时，在风向为210°左右地面涡强度达到最大，外物吸入能力最高，其导致的进气道出口周向压力畸变最强。该型运输机滑行状态相对于其静止、逆风环境，地面涡的范围、强度均较小，对进气道出口流场品质也影响较弱。

Abstract: Based on idle and engine driving of a military transport aircraft equipped with a large bypass ratio turbofan engine in unpaved runway ground,a full-scale three-dimensional simulation model was established, By means of numerical simulation, the ground vortex distortion flow characteristics under different wind speed, wind direction and running speed were studied. The result showed that the ground vortex intensity first increased and then decreased under the 270 degree crosswind condition. The ground vortex intensity was maximal under wind speed range from 2 m/s to 4 m/s. The ground vortex disappeared when wind speed was more than 6 m/s. The ground vortex intensity was maximal and it had strongest suction capacity to foreign objects at 210 degree wind direction under the wind speed of 3 m/s. Also it had greatest influence on the inlet's outlet flow field. The ground vortex intensity and scope was weak under the condition of aircraft running compared with stationary,headwind.
