The cannon caliber electromagnetic gun system is based upon a compulsator d
riven 30 mm rapid fire railgun system. The objective of the program was to
develop a compact, lightweight test bed capable of launching three, five ro
und salvos of 185 g integrated launch packages to 1.85 km/s at a firing rat
e of 5 Hz. Per contractual requirements, the pulse power system is also siz
e compatible with the Amphibious Assault Vehicle. The pulse power system wa
s developed around a fourth generation air-core, ii-pole rotating armature,
self-excited, compulsator design. Although the contract for this effort ha
s expired, the system continues to be used in part to demonstrate compulsat
or driven railgun technology. This system has performed seven single shots
using identical control settings for each shot, which is the first such exp
erience using a compulsator driven railgun system.
This paper describes the experimental set-up for the demonstrations and com
pares the generator, converter, gun switch, and launcher performances for e
ach shot.
