| 摘 要： | 采用CFD手段模拟了民机着陆时反推力系统打开后的全机流场,着重研究反推力系统工作时对发动机进气口流场的影响,并计算了不同状态下的进气口静态总压畸变指数,对全机流场进行了可视化分析,为民机发动机反推力系统设计提供生动直观的设计依据,也是CFX软件在全机复杂喷流N-S方程数值模拟中的成功应用。

| Abstract: | In this paper,an investigation into thrust-reverser flow on a landing twin-engine transport,which focused on the effect of thrust-reverser operating on the engine inlet flow on the landing transport aircraft,was conducted in FAI.At the same time,in order to provide lively and intuitionistic basis for thrust-reverser design,static total pressure distortion coefficients,IDC,were computed by a program,and flow visualization analysis was carried out through a successful numerical simulation using the CFX software. |

| Keywords: | thrust-reverser numerical simulation static total pressure distortion coefficient cascade visualization |
