To study the interior ballistic performance of charge for partially cut multi-perforated stick propellant, a interior ballistic simulation model of charge for partially cut multi-perforated stick propellant was established based on the classical interior ballistic theory. The calculation of interior ballistic performance of charge was performed using the partially cut multi-perforated stick propellant with high energy nitramine propellant formulations. The experimental validation were carried out on 30 mm artillery. The effect of incision intervals, incision web and incision depth on the interior ballistic performance of partially cut multi-perforated stick propellant was analyzed. The results show that the maximum bore pressure calculated by the established interior ballistic model of partially cut multi-perforated stick propellant is 430.2 MPa. The calculated error of the maximum bore pressure is 5.0% compared with average value of testing maximum bore pressure of 409.7 MPa. The calculated muzzle velocity is 1378.2 m·s^-1, and the calculated error is 2.2% compared with average value of testing muzzle velocity of 1409.6 m·s^-1. The maximum bore pressure and muzzle velocity decrease with the increase of incision intervals. When the incision intervals increase from 5 mm to 50 mm, the maximum bore pressure reduces by 12.0%. And the muzzle velocity reduces by 3.1%. The effect upon the interior ballistic performance is gradually reduced when the numerical value of incision intervals is greater than 20 mm. The value of maximum bore pressure and muzzle velocity increases with the increase of incision depth and incision web. The effect of incision depth upon the maximum bore pressure is more significant than that upon the muzzle velocity. The interior ballistic performance of the propellant is insensitive to the change of incision web′s value.
