THE DESIGN AND USE OF A BUOYANT MISSILE FOR THE RECOVERY OF ANGLED ARROW PROJECTILE COMPONENTS
Abstract
The buoyant vehicle was constructed to permit overwater test firing and recovery of 7-lb AAP sonde packages. Firing ballistics were simulated with a 105-lb round fired from an 8-in./55-cal smooth-bore gun at a 4000-fps mussle velocity. The 21-lb vehicle of 1.5-in.-thick sugar-pine planks glued with the grain parallel to the longitudinal axis had a positive buoyancy between 8 and 10 lb. Maple and aluminum were used for the front cover and rear plate, respectively. A slug which separated from the body during flight provided the required weight. The vehicles were wrapped in Fiberglas to prevent breakage during flight. Red dye aided in spotting the floating missiles. Tests indicated that the technique permits accurate simulation of actual loads, recording of generated sonde signals, and recovery and examination of the tested components for structural and functional failure.
