The Effect of The Nozzle Ultimate Section Diameter on Interior Ballistics of HV-76 Trial Gun

Abstract

The paper presents a system of differential equations to solve the interior ballistics of HV-76 trial gun [1], which uses the principle of high - low pressure weapon. The paper has researched the effect of the nozzle ultimate section diameter on the highest value of pressure in the high-pressure chamber as well as in the low-pressure chamber, and the muzzle velocity of the projectile fired from HV-76 trial gun to determine parameters of electronic fuse [7]. The results obtained of the paper were used as a scientific basis which helps to determine the reasonable parameter of the nozzle ultimate section diameter for design and manufacture of HV76 trial gun as well as other types of high - low pressure weapon.
