| Abstract: | The coupling solution of a transonic flow and a free oscillating reentry vehicle using numerical method is presented,the phenominon of equi amplitude pitching motion of reentry vehicle has been shown.The period of pitching motion is about 2.8 second,and the amplitude is about 6.0 degree.These results are almost same as that obtained in flight experiment and wind tunnel test. |
