绪言 随着自由飞行器的发展,常规火炮很久以前就变成了一种试验装置,即用于提供高速度弹丸。就一般火炮而言,它仅能提供2～3km/s的高速度弹丸,这个速度上限是由于火药气体分子量大造成的。如果使用氢气或氦气,由于它们的分子量小,就能得到较高的弹丸速度。 基于这种思想,1946年美国人研制了第一门利用轻质气体作发射气体的炮。以后,以轻质气体为工作介质的各种类型轻气炮装置相继问世。目前这种设备已经发展到可以产生高达11km/s速度弹丸的试验装置。
INTRODUCTION With the development of free-flying craft, conventional artillery has long been a test device for providing high velocity projectiles. As far as the general artillery, it can only provide 2 ~ 3km / s high speed projectile, the speed limit is due to the gunpowder gas molecular weight caused. If hydrogen or helium is used, higher projectile velocities can be achieved due to their small molecular weight. Based on this idea, in 1946 the Americans developed the first cannon to emit gas using light gases. Since then, light gas as the working medium of various types of light gas gun devices have come out. At present, this kind of equipment has been developed to test devices that can produce projectiles up to 11km / s.
