- In the structure of reducing the recoil force by jet gas for auto-weapon, the nozzle section is expansion. Within the nozzle, the state of nozzle flow will change, when high temperature and high pressure, high speed gunpowder gas get through the expansion section. The gas is directed to weapons rear through the nozzle, therefore, the objects of handheld or unmanned weapons are impacted by gunpowder particles spraying at a high speed from the nozzle. In order to analyze the safety of the jet flow field of unmanned automatic weapon, establish the axisymmetric two-dimensional model of the outer flow field. Analyze the results of numerical simulating calculation, find out the speed, pressure, temperature and other key parameters distributions of jet flow field and optimize the structure of nozzle and jet. Ensure recoil reduction l efficiency, at the same time ensure the safety.
