This paper presents an internal ballistics model for recoilless weapons in which the propellant gas flows out from the high-pressure chamber (HPC). The problem is solved using the numerical integration method in MATLAB software. The mathemat-ical model and experiment were used to determine the gas pressure in the HPC, low-pressure chamber (LPC), time and velocity of the grenade at the muzzle. The maximum difference between the results of the mathematical model and experi-mental data was found to be 7.92 % for both cases, where the initial temperatures of the propellant charge were set at 5 °C and 50 °C.
