Abstract. A study was conducted to compare the high velocity penetration
performance of segmented-rod projectiles of various spacer and segment lengths
with that of continuous rod projectiles of the same mass
and diameter. A high-pressure pre-burned propellant gun was built for
this study. Analytical models by Tate and Charters were used
to predict the penetration performance. Computer simulations using the AUTODYN
2D package were run to study the penetration process. It
was predicted that at velocities around 1800 m/s and above,
the performance of the steel-segmented rods was much superior to
continuous rods. In trials, a 5-segment rod, with spacing of
l/d =2.25, fired at 1800 m/s, achieved a penetration performance
44% higher than continuous rods of similar mass and diameter
fired at similar velocities. Simulation of segmented projectiles with 10
segments, compared to continuous rod of similar mass and diameter,
impacting at 3000 m/s, produces an increase of 59% penetration.
