• To develop and validate a coupled model simulating the artillery launching process with the barrel gas reflection device.
• To establish a quantitative relationship between design parameters and performance outcomes.

Main Methods:

• Coupling interior ballistic equations with barrel gas reflection device flow equations for simulation.
• Employing the fourth-order Runge-Kutta method for model solution.
• Utilizing Latin Hypercube Sampling (LHS) and Kriging methods for parameter-effect mapping.
• Conducting shooting experiments on a 30 mm caliber artillery for model validation.

Main Results:

• The simulation model achieved a maximum error of 5.32% compared to experimental results.
• The barrel gas reflection method demonstrated a 44.54% increase in recoil reduction efficiency.
• Muzzle hazard was reduced by 52.18% using the proposed method.
• The method showed minimal impact on projectile muzzle velocity.

Conclusions:
