Abstract : Tests were conducted to determine the minimum thickness of the aluminum target and the maximum able of obliquity against which the T-2027 fuze will fuction, the impact delay time against minimum and maximum target thicknesses, and the impact delay times with the fuze conditioned at high and low temperatures. The T-2027 fuze was essentially the same as the Mk176 or EX- 100 fuze with the explosive loading in the rotor changed to an obturated primer and detonator with an air gap between them. The firing pin was modified to have a hemispherical tip rather than a point. The 2.75-in. heads were assembled to 5- in. HVAR motors by use of special aluminum adapters. A second 5-in. HVAR motor was used in tandem as a booster to obtain higher striking velocity and increase the acceleration period of the rounds. This fuze requires a minimum acceleration of 20 g's to be maintained for at least 1 sec or it will not arm. When fired for target impact at velocities of approcimately 2100 fps. the T-2027 fuze wull function with reasonable consistency on: 0.020-in. or heavier aluminum alloy at 60 obliquity at ambient and elevated temperatures; 0.080-in. or heavier aluminum alloy at 0 obliquity at -30 F, and 0.250-in. aluminum alloy or mild steel at temperatures ranging from -30 to 130 F. When detonating after impact on targets 0.125 in. and thinner, the fuze usually has a delay greater than 500 mu sec; when detonating on targets 0.250 in. and heavier it often has a delay less than 500 mu sec.
