ANALYSIS OF THERMAL AND GAS-DYNAMIC CHARACTERISTICS OF DIFFERENT TYPES OF PROPELLANT IN SMALL WEAPONS

ABSTRACT
This paper presents a numerical and an analytical approach for calculation of internal ballistics parameters through determination of thermal and gasdynamic characteristics. The calculated parameters are validated through experimental tests on a real weapon system. The internal ballistic calculations are provided for two types of propellants using an analytical and a numerical model. Calculations and tests are performed for an anti-material rifle 12.7 mm. Weapon and ammunition testing is carried out according to the permanent international commission standard. Theoretical and experimental results for the gunpowder gases pressure and the muzzle velocity are compared. The good agreements between the calculated and the measured pressures and velocities increase the reliability of the estimated gunpowder gas temperatures in the barrel. The obtained results enable analysis and comparison of the output internal ballistics parameters for different types of propellant applications.
