Experimental determination of ignition and combustion characteristics of insensitive gun propellants based on RDX and nitrocellulose

Safety improvements in the field of energetic materials led to development insensitive gun propellants. This article deals with ignition and combustion parameters two commercial propellants, respectively based on RDX nitrocellulose. Ignition is obtained thanks a laser diode probabilities are given, along delays, overpressures propagation rates. Experiments performed under nitrogen argon atmospheres, initial pressures ranging between 10 70 bar powers 0.66 9.95 W. It found that enhances combustion, especially but not delays more sensitive powers. Nitrocellulose-based propellants be reactive than RDX-based ones. Results graphitized laboratory same also given discuss results.
