Abstract
A new generation of gun propellant, named Modified Single Base Propellant (MSBP), was successfully studied recently. The MSBP was prepared from single base propellant grain by impregnation with blasting oil, followed by deterring with deterrent in water medium. The function components in this propellant were nitroglycerine (NG) and polymer ester (NA). The concentration profiles of them were studied by Fourier Transform Infrared (FTIR) Microspectroscopy. The combustion performance of this propellant was investigated by means of closed-bomb tests and interior ballistic tests. It is found that the concentration profile of the function component is the key factor in MSBP. The static combustion performance and the characteristic of the interior ballistic are dependent on the concentration profile of function component.
