air and in the presence of a partial model of the B-52B airplane. The objectives of the test were to obtain force and momentdatatogeneratestructuralloadsaffectingthepylonoftheB-52Bairplaneandtodeterminetheaerodynamic influence of the B-52B on the Hyper-X launch vehicle for evaluating launch separation characteristics. The windtunnel test was conducted at a low-speed wind tunnel in Hampton, Virginia. All moments and forces reported are basedeitheronthe aerodynamic influenceof theB-52B airplaneorarefor theHyper-Xlaunch vehicle infreestream air. Overall, the test showed that the B-52B airplane imparts a strong downwash onto the Hyper-X launch vehicle, reducing the net lift of the Hyper-X launch vehicle. Pitching and rolling moments are also imparted onto the booster and are a strong function of the launch-drop angle of attack.
