Abstract:

Techniques were developed to launch 25g LD 10 rods from a 50mm propellant gun. The rods were S-7 tool steel, W-Ni-Fe alloy, and Co-bonded WC. The velocities were in the range 1.8 to 2.58 kms. The rods were launched against 25.4mm 4340 steel plates at 0 deg and 45 deg obliquity, and four 6.35mm 2024 T3 aluminum plates. Behind-target fragment data were obtained by flash x- ray analyses, witness plate measurements, and recovery of fragments.
