Therefore, combustion performance is not only one of the most important performances of the propellant, but also affects the basic properties of the weapon system directly, such as velocity, range, accuracy and security.
In order to adjust the relationship between the energy, explosiontemperature and the affect of flame added a small amount of auxiliary additives.
Used the scanned electron microscopy (SEM) to observe, studied their internal microstructures and the cause of the mechanical properties anisotropy.
In the molding process after the propellant extrude, through nitrocellulose macromolecular will produce a certain amount of relaxation, unorganized and decentralized diffusion motion, but as the system is used half solvent method, including solvents and plasticizer content rarely, viscosity is so high that the state is a solid sol, so the orientation state is largely preserved, leading to the anisotropy of mechanical properties of the propellant.
These factors change, the shrinkage rate of gunpowder will follow to change.
