Aerodynamic and Aerothermodynaemic Studies on the Hasp 1.0-inch Diameter Dart

Abstract

The High Altitude Sounding Projectile, HASP, has been the subject of a design study aimed at enhancing the round's performance. The techniques used and the results obtained from this study are described. It was found that by decreasing the dart's diameter to 1.0-inch and using the standard MK 32 MOD O HASP motor, altitudes of the order of 300,000 feet could be achieved. Besides scaling down the present 1.375-inch diameter dart the following significant changes are required; an increased static margin. a decreased fin-cant angle, use of a fin material whose strength does not materially deteriorate at elevated temperatures, and thermal protection for the motor casing.
