Development of XM714A3 Delay Function Fuze
Abstract
This report documents the advanced engineering of the XM714A3, a delay version of the XM714 fuze family. The fuze was characterized to provide delay function of a light weight thin-wall 20mm High Explosive Incendiary (HEI) projectile to be used for air-to-air combat missions. The program objectives were met within the defined schedule as summarized: A function delay of 10 + or - 4 inches (9 inches, nominal delay required) was demonstrated at 0 to 80 degrees obliquity, 2500 to 3500 ft/s impact velocity against 0.06 - to 0.125- inch 2024-T3 aluminum targets. The fuze was packaged within the 1.2-inch-long ogive profile. Bore safety and reliable arming within 100 feet was provided. Selected MIL-STD-331/MIL-STD-810B safety requirements were demonstrated. No self-destruct and no function against simulated rain target was demonstrated. Projectile length, protrusion, weight, and charge-mass ratio (C/M) requirements were met. Five hundred XM714A3 fuzed projectiles were shipped on schedule and successfully demonstrated the performance envelope of the fuze in a test series conducted by the Air Force. A unit product cost estimate for the fuze was generated and furnished to the Air Force.
