| Abstract This work was carried out to study the possibility of using double base propellants in guns working with single base propellants and vice versa. This was done through studying the effect of changing powder type on the internal ballistics parameters (gases pressure, projectile velocity and gases temperature) through the gun barrel with changing the grain configuration. Two types of guns were studied (155mm howitzer and 100mm field guns) with two types of powder (single base -M1-MIL-P-309- and double base -M8-JAN-P-381- propellants). Three grain configurations (cord, stripe and single perforated grains) were used for different cases. Computer program (MATLAB) was used to obtain the required results after checking the reliability of the program. The results emphasize the effect of changing powder type on the ballistics parameters through the gun barrel. It was found that it is possible to obtain the required muzzle velocity without exceeding the maximum gases pressure by adjusting the dimensions of powder grains and weight of propellants putting in mind the length of barrel. | ||||
