    Abstract
  • Fixed refueling pipe added to a fighter induces an obvious increase of the cabin noise. In order to reduce the noise, the changing laws of the cabin noise was tested in flight, then the reason of noise increase was investigated by flow field visualization tests and turbulent flow measurements in wind tunnel. After the design of refueling pipe was modified according to the results of present study, the cabin noise was obviously reduced.
