Study of Influence on Auto-Weapon Launching Performance by Nozzle Structure

Abstract:

Technology of reducing the recoil force by jet gas is a new effective technology to reduce recoil in recent years. In order to understand deeply the influence of Laval nozzles structure to achieve low recoil force on auto-weapon, two-phase flow model was developed and a machine gun as the experiment object was used for numerical analogy, analogy the influence of the efficiency of recoil reduction about nozzle angle and nozzle length, etc.
