PDADN在螺压硝胺改性双基推进剂中的应用研究

Application of PDADN in Screw Extruded Nitramine Modified Double-base Propellant

为改善硝胺双基推进剂的综合性能,对季戊四醇二叠氮二硝酸酯(PDADN)在螺压硝胺改性双基推进剂中的应用进行了研究,测试了推进剂的力学性能、燃烧特性、化学安定性、机械感度、能量特性和燃气特征信号,对比分析了试验数据。研究结果表明,PDADN新型含能材料的引入不仅可以显著改善推进剂的力学性能,而且对提高推进剂的能量、降低燃气特征信号及燃烧温度等均有益。

In order to improve the comprehensive performance of nitramine double-base propellant, carried out application of pentaerythrite diazidodinitrate （PDADN） in screw extruded nitramine modified double-base propellant was studied. The mechanical property, burning characteristics, chemical stability, mechanical sensitivity, energy characteristics and gas characteristic signal of propellants were measured. Results show that use of the new-type energetic material not only improves mechanical property of propellants, but also is beneficial for increasing propellant energy and decreasing characteristic signal of burning gas and burning temperature.
