| Abstract: | Air refueling ability is one of the most important characteristics of modern f ighters. As a kind of fixed refueling pipe was added to a fighter, it induced an obvious increase of the cabin noise. In order to reduce the noise, we studied a nd compared the characteristics of flow around three kinds of pipes by CFD and t urbulent flow measurement in wind tunnel. Then the study result was verified by flight test and the cabin noise was reduced obviously. |
