THE RELATIONSHIP BETWEEN GAS PRESSURE WITH DIMENSIONS OF GAS HOLE FOR THE RPD GUN

Abstract

The article shows the relationship between gas pressure in the air chamber and the size of the gas hole of the RPD automatic gun. Originally from the calculation of pressure in the barrel of the RPD gun, based on the value pressure at the extracted position the pressure in the air chamber is calculated. There are three air gas holes with different width, they are 1.5mm; 2.0mm; 4,0mm, each hole has a different pressure distribution. However, these pressure characteristics are uniform. The newspapers provide a reference for students in the study, research.
