| ABSTRACT Automatic weapons are considered as an internal combustion engine, where the driving energy is supplied from the burning of the smokeless propellant charge, it burns producing tremendous power of hot gases. This power is extensively used in driving of projectile through the barrel, and the motion of weapon mechanisms that leads to the full automation of weapon functions. In order to achieve the second goal of gases usage, a constructional arrangement is fixed on weapon barrel, this arrangement allows gases to branch and drive the main moving weapon component, this component is known as the breech block carrier [1]. The motion of which is responsible of moving all other mechanisms in automatic weapon. The regulations and controlling over the output from the gas unit are affected basically by the changes of the geometrical characteristics of the gas unit. In this work, the variations of these geometrical parameters of the gas unit and their reflections on its efficiency have been studied. The present study facilitates the choice of effective parameters specially when designing a new weapon or modifying the power of an existing weapon. | ||
