Cylindrical and boat-tailed afterbodies in transonic flow with gas ejection

The measurements were made in an intermittent ejector driven 9 X 8 in. perforated wall transonic wind tunnel with atmospheric stagnation pressure and Reynolds number of 4 X 10/ft. The model consisted of a 1 in. diam 5 caliber centerbody and interchangeable 2 caliber afterbodies. The centerbody was supported on a pair of 45° swept forward hollow struts (see Fig. la), one strut contained pressure tubes
