PERFORMANCE OF TRAILING AERODYNAMIC DECELERATORS AT HIGH DYNAMIC PRESSURES. PHASES V AND VI

Abstract

A series of multistage rocket test vehicles was launched which deployed aerodynamic decelerators at predetermined altitude and velocities. Tests were conducted using extended hemispherical shaped parachutes. Exploratory test were accomplished and data collected over a test regime extending up to Mach 3.0 at 70,000 ft. In addition, data was presented on one test of a FIST ribbon parachute deployed at an altitude of 162,990 ft. and a Mach number of 1,022. Data was also presented on 2 tests conducted involving balloon type decelerators. Useful test data was presented for each parameter investigated. It was concluded that self inflatable aerodynamic decelerators perform satisfactorily up to a Mach number of approximately 2.0. At higher Mach numbers the flow conditions and shock wave interactions caused erratic performance which resulted in canopy damage of considerable magnitude. (Author)
