Drag data were obtained at Mach numbers 0.5, 0.8, and 1.2 for the ballute decelerator in the wake of the payload of the Air Launch Air Recovery Rocket (ALARR). Two model sizes of the ALARR payload were tested at angles of attack of 0 and 20 deg placed at 2, 3, 4, 5, and 6 payload diameters forward of the decelerator. The decelerator remained at zero angle of attack. The wake influence of the larger payload reduced the drag of the decelerators, both at 0- and 20-deg angles of attack. In addition, static stability characteristics were obtained on the ALARR payload for a Mach number range from 0.5 to 1.5 and an angle-of-attack range from -4 to +22 deg. To maintain static stability the center of gravity cannot move more than 29% of the model length aft of the nose. (Author)
