A gas pipe lightweight and advantages of the acceleration of a solid object, by means of such a gun, a gas lightweight

摘要

The gun has propulsion tubes (30a, 30b) respectively comprising pistons (40a, 40b), and a high pressure part (50) serving as stop for the pistons. The pistons are guided in a displaceable manner for compressing light gas enclosed in respective propulsion tubes when ends of the propulsion tubes are connected to the high pressure part. The high pressure part is provided with a mass e.g. projectile. The projectile is accelerated by expansion of the gas in an expansion chamber (20), by compression of light gas in the tubes, and by introduction of compressed light gas in a gun tube (60). An independent claim is also included for a method for accelerating a mass.
