Experimental measurements of blast wave overpressure and specific impulse are usually used for blast performance analysis of energetic materials. Such results are important to represent their damage effects. Propellant detonation and blast properties data are scarce, so experimental research was done using domestic gun propellants with nitrocellulose and nitroglycerine as main energetic components. Cylindrical charges with different propellants were considered in present study. Charges had equal length and diameter, 0.5 mm thick paper casings and were loaded with 400 g of propellant. Propellants considered had different nitroglycerine content, ranging from 0 to 40.5 mas. %, as well as different grain shape and dimensions. They were detonated using standard electric detonators and spherical booster charges with 15 g of PETN-based plastic explosive. Experimental blast wave profiles were recorded using pressure sensors 137B24A and 113B51, manufactured by PCB Piezotronics Inc. Charges and measuring sensors were placed 2 m above ground, in order to minimize effect of wave reflection. Experimental data was analysed in order to obtain correlations of blast performance parameters on different properties of propellants.
