The design and construction of a 50 mm bore laboratory gas gun capable
of velocities up to 1000 m s(-1) is described. The performance of the
gun is compared with the analytical interior ballistics model of Pidd
uck and Kent. The adaptation for one-dimensional plate impact experime
nts, the instrumentation employed and the capabilities of the system a
re described, and some examples of experimental results obtained are g
iven.
