RESEARCH ON THE INFLUENCE OF SOME FACTORS ON THE DEPARTURE ANGLE OF WARHEADS WHEN FIRING A SERIES
Journal Title: Engineering and Technology Journal - Year 2023, Vol 8, Issue 11
Abstract
In this article, the equation for determining the projectile's departure angle taking into account the effects of several shot parameters is established. The parameters of the shot include the speed of rotation around the axis of the rotating part when fired; and the curvature of the barrel due to the temperature of the shot. Numerical calculations are applied to 37mm anti-aircraft guns. Research results show that: The speed of rotation around the axis of the rotating part when firing has a significant effect on all types of artillery, especially on long-barreled artillery; While the shot temperature significantly affects the departure angle of the warhead when firing in series. This influence causes errors in the firing. The departure angle becomes larger as the rotation speed becomes faster; The departure angle of the bullet when firing the 5th, 10th, and 15th bullets is 0.0117, 0.015, 0.0175, 0.0185, 0.0199, and 0.0206 rad, respectively, when taking into account the shot temperature. This result is used as data to provide effective barrel design solutions and barrel cooling methods
