Paper Abstract

A new concept for accelerating projectiles to ultra high velocities is described. The concept, termed BASH, rapidly (milliseconds) heats a hydrogen U235 mix-ture in a pulsed nuclear reactor. The hot high pressure propellant, which has a sound speed of .'20 km/sec, then accelerates a 2 kilogram projectile in a conventional gas-gun type barrel to a very high velocity, 30 km/sec or more. The BASH gun can fire at a rate of several Hertz, if desired. Features of the BASH gun are described, along with trade studies of performance and a 30 km/sec baseline design. Technical issues are discussed, including protection against high convective and radiative heat transfer rates.
