Title Compressed air type simple general emission device structure design
Abstract
Traditional rocket missile launch system most used as a source, gunpowder that was first lit by the high speed gas tracer will rocket or missile pop up (frame), and then carry through the projectile rocket engine continues to target.And in the process of launch, detonating gunpowder (or other combustion agent) generated by high temperature and high pressure gas will first ablation orientator, often leads to process more complex tracer to launch a second time, cause waste and raise the cost of recycling field. Secondly, high temperature and high pressure gas will produce disturbance to launch system, it is fatal for multiple rocket weapon. First rockets after the launch of the high pressure gas generating behind all the rocket launch with initial disturbance, increase the computing workload, and the fire control system delay the launch of a second hair play time, increasing the risk of fire positions exposed. Therefore launch system, the design USES cold means of transmission for compressed air as working medium, a simple design general launcher emission structure scheme.

1 绪论
1.1 研究背景
当前常规火箭武器是引燃火箭发动机点火具，赋予火箭弹初始方向的发射装置，它与身管武器相比有许多优点，比如射程远且威力大、机动能力强，但也存在很大缺陷，最为致命的为发射阵地容易暴露。造成这个缺陷的主要原因是火箭武器在射击时产生大量的烟尘火光，不易隐蔽。特别是遮蔽物较小，射程较近，发射阵地靠前或夜间射击时，由于传统发射方式为点燃点火具所致，容易招致敌人的炮火反击。因此世界各国在上世纪提出了冷发射方式。
将导弹（火箭）依靠外加动力进行发射的方式称为弹射，弹射技术又叫做冷发射（cold launch），它是相对于导弹（火箭）的自行点火发射而言的。冷发射技术是从20世纪50年代末期，为了满足潜艇水下发射鱼雷的需要而发展起来的，随机推广用于导弹的水下潜艇发射和井下发射，在各类舰载、路基发射中也得到广泛应用。
