| Abstract: | The sonic load test data of the vertical tail of F-7 aircraft are analysed and the acoustic pressure distribution law is found from test data.When the sound sensors were installed in a distance less than 5cm from the surface of the tail, the measured data in ground test can substitute those from flight test. |
