摘要

The modern war requires continual improvement of the weapon shooting precision. Especially in multi-barrel weapons, there are so many factors affecting the shooting precision, such as the muzzle flowfield disturbance between different projectiles. Firstly a mathematical model of muzzle flowfield coupling with the interior ballistics process was established, and the simulation was conducted in a small caliber gun in which the finite volume method was used to solve the muzzle flow on the 2d unstructured grids. The numerical results are consistent with the experimental ones. Then, flowfields of two barrel gun was simulated, and the effects of barrel distance, firing delay between different projectiles on shooting precision were also discussed.
