Abstract

The R1, R2, R3 test samples based on the high-energy gun propellant R0 were prepared by adjusting the volume ratio of solvent, nitrogen content of nitrocellulose(NC) and mass ratio of 1, 5-diazido-3-nitrazapentane (DA) and nitroglycerin(NG). The structural change and anti-impact fracture property of gun propellants after impact were studied via drop hammer test, closed bomb test and scanning electron microscopy. The results show that under the conditions of constant total content of blending plasticizer, the increase of mass ratio of DA and NG may significantly improve the anti-impact fracture property of gun propellant at lower temperature of -40°C and the fracture degree of propellants may reduce from 3.27 to 1.19. The decrease of nitrogen content of NC or increase of acetone content in solvent are beneficial to improve the anti-impact fracture property of gun propellant.
