| Abstract: | Black powder is usually used as propellant in fireworks industry. To solve problem of the huge smoke produced in fireworks, a new smokeless propellant was designed with the formula of: NC 77%, NH4ClO4 13%, HTPB 5% and deterrent material 5%. Its ignition and working capacity, smoke performance and mechanical sensitivity of smokeless propellant were tested and compared with that of black powder. Results show that the smoke volume of smokeless propellant decreases by 79.5% compared to black powder. The ignition has been delay time and pressure impulse of smokeless propellant are 72.7 ms and 320.0 MPa·ms, which indicates the ignition performance has been improved. The working capacity is increasd by 28% compared with black powder. The mechanical sensitivity meet the requirements of propellant used in fireworks. |
