✦ Synopsis

We have modified the design of an explosive gun launcher described at the Third Symposium on Hyperveloclty Impact for use with pro-cast explosive charges and to provide performance Information for steel projectiles.

Other modifications include additional confinement of the detonation products, a longer barrel and longer conlcal transition leon breech to barrel, provision for dynamlc seallng of the access hole for the detonator wires, and additional buffering to prevent spall fracture of the projectile In the barrel.

The modified gun launched a 12.1 gram steel projectile to a measured velocity of 3.2 kn/s.

Computational alm~lattons have been performed to determine the effects of changes in the projectile density, confinement material density, and explosive type.

The use of recyclable confinement material is discussed.

Recently, hypervelocity impacts between space structures and space debris have been brought to attention with the advance of space development. The impact velocity at low earth orbit (LEO) is up to 15 km/s. Such impact velocity cannot be attained by the current two-stage light gas gun (TSLGG). There
