Title 40mm triple shooting artillery
Abstract
It is great significance to improve the rate of fire and starting shooting . This new Design is about a new 40mm artillery which can complete triple shooting. Based on the analysis of new 40mm artillery working,design the new 40mm artillery barrel,the connecting member and so on. The new triple shooting artillery use a new breechblock which can traverse,filling Cased Telescoped Ammunition,trying to solve some problems by bold innovation.This design have a special breechblock which can load three bullet after only one move,by breechblock's movement to achieve triple shooting.This structure have the special require for barrel and breech . Analysing the known parameter to calculate barrel's pressure when you design, then check strength,choose material which haven known. Finally,complete the task requirements.
Keywords Triple shooting Cased Telescoped Ammunition Barrel Breech Check strength
