Abstract:

This report describes the research and development of a molded plastic overlay shell for the XM74 Grenade Improved BLU-63 Munition to provide fins of a very sharp definition, required toughness, and improved aerodynamic characteristics for the ARRADCOM version of the grenade with a pre-engraved sintered tungsten shell for increased terminal effects. Aerodynamic analysis of the grenade with the BLU-26 fins confirmed the improved aerodynamic flight characteristics, and laboratory tests proved the required toughness of the molded plastic overlay. Tests conducted included pull apart at room and high temperature, simulated launch load at high and low temperature, impact at three temperatures, simulated storage, impact and pull apart after simulated storage, and burial tests. The design of the plastic overlay and crimp strap for tested grenades was documented, and the manufacturing process was defined. Burial tests were run on BLU-63 and Improved BLU-63 with standard and modified M219A1 fuzes. No significant difference in burial depth at time of function was noted. Author
