| 摘 要： | 针对运输机的翼/身/架/舱干扰问题,本文基于Euler方程,采用笛卡尔直角网格,应用有限体积法对全机绕流流场进行数值计算,分析和比较了短舱挂架不同前伸量、下沉量的影响,提出了基于最佳前伸量和下沉量的优选配合位置,并与初始位置的全机气动特性进行对比。结果表明,获得的短舱挂架优选配合位置使全机气动特性得到了明显改善和提高。 |
| 关 键 词： | 翼/身/架/舱干扰 Euler方程 前伸量 下沉量 优选配合位置 |

| Abstract: | To resolve the problem of the interference between the wing/body/pylon/nacelle of the large transport aircraft,this paper uses the Euler equation with the Cartesian grid and finite volume method to calculate the flow characteristic of the aircraft with different amounts of protrusion and subsidence of the nacelle and pylon,also analyse and compare the aerodynamic performance.The optimized position is selected and demonstrated.The numerical result shows that the aerodynamic performance of the transportation ... |
| Keywords: | the interference of the wing/body/pylon/nacelle Euler equation amount of protrusion amount of subsidence optimized association position |
