Machine Guns
Introduction
To understand how machine guns work, it helps to know something about firearms in general. Almost any gun is based on one simple concept: You apply explosive pressure behind a projectile to launch it down a barrel. The earliest, and simplest, application of this idea is the cannon.
A cannon is just a metal tube with a closed end and an open end. The closed end has a small fuse hole. To load the cannon, gunpowder (a mixture of charcoal, sulphur and potassium nitrate) is poure..............etc

INTRODUCTION
Since the conventional solid gun propellants have reached the saturation level in terms of energy output, a need exists for the development of high performance propellants for futuristic gun ammunition to propel hypervelocity projectiles. Hypervelocity guns are the guns having muzzle velocity in excess of 2000 m/s. Modern tank guns have muzzle velocity in the range of 1600 “ 2000 m/s. With continuous improvement in armour technology, improved weapons with high muzzle velocity are under..............etc

THE PROPULSION SYSTEM FOR FUTURISTIC GUN AMMUNITION
ABSTRACT
For the survival of human race, the greatest objective is to defeat the enemy. For this we have to design and bring modern concept for propellant system used in futuristic gun ammunition. To bring the concept into a success we have designed the gun ammunition with muzzle velocity excess of 2000 m/s. and with key objective over high range quicker response to time and better accuracy. The system has to be so designed that it can tackle the gun erosion. Propellant system used in balli..............etc
