火炮从其发明至今一直是用固体物质作发射药的,这样的火炮有两个明显的缺点:首先,由于固体发射药是装在药筒里的,药筒不但占据了炮弹的相当一部分重量和尺寸,还限制了火炮的安装和使用。其次,固体发射药的爆温高,给火炮造成的烧蚀严重。由于上述缺点靠固体发射药自身难以克服,因此人们希望能够开辟一些新能源代替固体发射药。液体发射药概念就是在这样的背景下问世的。 Artillery has been using solid materials as propellant since its invention so far. Such artillery has two obvious drawbacks. Firstly, since the solid propellant is contained in a cartridge, the cartridge not only takes up a significant portion of the weight of the shell and Size, but also limits the installation and use of artillery. Secondly, the high temperature of solid propellants has caused serious ablation caused by artillery. Because of these shortcomings by solid propellant itself difficult to overcome, so people hope to be able to open up some new energy sources instead of solid propellant. The concept of liquid propellant came out in this context.
