APPLICATION OF PRE-IMPULSE IN THE DESIGN OF AUTOMATIC WEAPONS BASED ON THE FREE BREECH PRINCIPLE

Tóm tắt

The article develops a dynamic model of a free-breech automatic weapon incorporating a pre-impulse using early ignition based on the law of conservation of energy. The results of the study demonstrate thatapplying a pre-impulse through early ignition before the breech reaches itsuppermost position allows for a reduction in the breech's mass, lessens the impact between the breech and the receiver at both the rearmost anduppermost positions, thereby reducing the force exerted on the mount and increasing the weapon’s stability during firing. At the same time, it ensuresthe weapon’s tactical and technical performance remains within acceptable limits. This serves as a basis for the application of pre-impulse in the design calculations and improvement of automatic weapons operating on the freebreech principle.
