Slingatron: A High Velocity Rapid Fire Sling

The mechanics of a spiral slingatron mass accelerator is discussed, together with some experiments to measure the sliding friction and mass loss of projectiles in such a machine. The potential utility of this machine for defense applications is also discussed, including examples of 1 kg and 50 kg projectiles launched at 3 kmsec. The device appears capable of high launch velocity with repetitive fire without over-heating the steel guide tube, since hot high-pressure gas is not used. It could derive power from a turbine that burns kerosene and it fires projectiles without propellant cartridges. Angular dispersion of emerging projectiles can be minimized, but would be larger than for conventional guns. However, projectiles that are smart enough to reduce dispersion of the projectile stream would suffice for many applications. Smart projectiles would also be needed for any gun capable of the long-range missions available due to high launch speed.
