Abstract : Investigations were conducted in the 16-ft supersonic wind tunnel of the Propulsion Wind Tunnel Facility to determine the drag and stability characteristics of a ballute deployed in the wake of a full-scale Air Launch, Air Recoverable Rocket (ALARR) payload. The ballutes were deployed at Mach numbers 0.55 and 2.00 to 3.00 and exhibited excellent deployment and inflation characteristics. Force data were obtained on a 0.6-scale model of the ALARR booster with a modified speed brake at Mach numbers from 1.80 to 3.00. The booster with speed brake was statically stable in pitch for all Mach numbers tested.
