Slingatron: A High Velocity Rapid Fire Sling

The dynamics and mechanics of the spiral slingatron mass accelerator are discussed, together with results from experiments to measure the projectile sliding friction, mass loss, and containment in the curved guide tube used in such a machine. The spiral slingatron appears capable of accelerating a stream of projectiles to very high velocity without overheating the steel guide tube because hot, high-pressure gas is not used. It could derive power from conventionalmotors such as a turbine that burns kerosene and would re projectiles without propellant cartridges. The machine has potential applications in areas of industry, defense, impact physics research, and space. Angular dispersion of emerging projectiles can be minimized, but would be larger than for conventional guns. Thus, for some defense scenarios, smart projectiles might be launched that on approach spawn many dumb impactors to shotgun a target. Smart projectiles would also be needed for any gun capable of the long-range missions available due to high launch speed.
