This paper presents an internal ballistics model for recoilless weapons with a high-pressure chamber, in which the chamber moves relative to the grenade. The model can also be applied to other scenarios, including a stationary high-pressure chamber, flowing out from high and low-pressure chambers, or a high-pressure chamber moving together with the grenade. The problem is solved using the numerical integration method in the MATLAB software. The maximum difference between the results of the mathematical model and experimental data was found to be 8.48% for both the case of a moving high-pressure chamber and a stationary chamber.
