Abstract : Tests were conducted which demonstrated the feasibility of employing the free-flight technique in a ballistics range to non-destructively test navel ammunition fuze components. Three models containing either an actual or dummy fuze clock were launched in the Naval Ordnance Laboratory's Pressurized Ballistics Range. Each model was launched at 2850 feet per second, a spin rate of 73 revolutions per second, and an axial acceleration loading of 18,000 g's. These conditions simulate those encountered during the firing of a 53/38 naval gun. Two models were recovered. One of these contained an actual fuze clock which was recovered virtually undamaged. Average deceleration loading for this recovery was 3000 g's. A wider range of launching conditions can be provided to simulate a great variety of firing simulations. In addition, lower recovery loadings appear practicable. (Author)
