Effect of vent hole size on combustion and explosion characteristics during cook-off tests

The unusual effect of paraffin wax on the thermal decomposition of cyclotetramethylenetetranitramine

“…Less released energy means lower reaction intensity and better slow cook-off performance and vice versa. [25][26][27] Recent experiments reported that the more gas generated by decomposition before thermal runaway, the greater the pre-damage caused and the lower the reaction intensity of slow cookoff. [28][29][30][31] Since the explosives rapidly combust and explode aer entering from thermal decomposition to thermal runaway, the thermal pre-damage before this signicantly inuences the intensity of the reaction.…”

Efficient Construction of MXene/V2O5 Nanocomposites for Optimizing the Combustion of Ammonium Perchlorate-Based Composite Solid Propellants

“…CSPs are also regarded as one of the most important energetic materials in the aviation field . Based on the special application field of CSPs, their energy performance, especially combustion performance, will directly affect the payload capacity and launch distance of the aircraft. , Based on this, improving the combustion performance to achieve greater energy load with less mass ratio of CSPs is very necessary. , The most commonly used CSPs are ammonium perchlorate/hydroxyl-terminated polybutadiene (AP/HTPB) propellants, which are based on AP as the oxidant and HTPB as the adhesive. , AP/HTPB propellants exhibit excellent energy characteristics and mechanical properties, which are widely used as a power source of military and civil aircraft. , Generally, the ratio of AP in AP/HTPB propellants is over 70 wt %, which means that the thermal decomposition performance of AP seriously affects the combustion performance of the composite propellants. , The recognized and simple method to ameliorate AP thermal decomposition is to use catalysts as the additives. − Therefore, finding suitable catalyst materials has become a focus of research in the application field of AP/HTPB propellants. , …”
