STUDY ON THE INFLUENCE OF THE NOZZLE PROFILE ON THE RECOILLESS CONDITION OF THE RECOILLESS GUN

Abstract

In this paper, a mathematical model was built to determine the recoilless
condition of the recoilless gun according to the structural parameters of the
nozzle. The investigation of the recoilless condition of the artillery is carried out
when changing the diameter of the critical section dth and the section at the outlet
of the nozzle da. Numerical calculation applied on recoilless gun DKZ-82mm. The
calculation result is the law of the recoil force R according to dth and da. This result
is the theoretical basis to determine the critical cross-sectional diameter and the
diameter at the outlet of the nozzle to ensure no recoilless condition for the gun.
