Abstract In this study, a new monopropellant which consists of ammonium dinitramide (ADN) water solution and tetraethylene glycol dimethyl ether (Tetraglyme) fuel is reported. The purpose of research was to improve the specific impulse and to compensate for the preheating temperature and vapor pressure of LMP-103S (63 wt% ADN, 14 wt% water, 18.4 wt% methanol, and 4.6 wt% ammonia). Methanol, ethanol, acetone, and glycerol were also used as the organic fuels to prepare the ADN based monopropellant with and without ammonia solution. Further, the characteristic properties and performance of ADN based monopropellants were determined and compared with each other. The thermal properties and explosive power of those monopropellants were performed by using thermogravimetric analysis and differential scanning calorimetry (TGA-DSC) analysis and the blasting cap test, respectively. The TGA-DSC analysis revealed that a catalyst active material was an important factor more than the flash point and auto-ignition temperature of fuel for the propellant's preheating temperature. The ADN based monopropellant mixed with tetraglyme exhibited a similar explosive power as with the LMP-103S. Moreover, the theoretical vacuum specific impulse of the propellants mixed with tetraglyme was of 1–6% higher than the propellants with other fuels. Overall, ADN water solution blended with tetraglyme may be one of the promising fuel candidates for the satellite application.

与四甘醇二甲醚混合的另一种基于 ADN 的单组元推进剂

摘要 本研究报道了一种由二硝胺(ADN)水溶液和四乙二醇二甲醚(Tetraglyme)燃料组成的新型单组元推进剂。研究的目的是提高比冲量并补偿 LMP-103S(63 wt% ADN、14 wt% 水、18.4 wt% 甲醇和 4.6 wt% 氨)的预热温度和蒸汽压。甲醇、乙醇、丙酮和甘油也被用作有机燃料,以制备含氨溶液和不含氨溶液的 ADN 基单组元推进剂。此外,确定并相互比较了基于 ADN 的单组元推进剂的特性和性能。分别采用热重分析和差示扫描量热法(TGA-DSC)分析和爆破帽试验对这些单组元推进剂的热性能和爆炸威力进行了测试。TGA-DSC分析表明,对于推进剂的预热温度,催化剂活性材料是比燃料的闪点和自燃温度更重要的因素。与四甘醇二甲醚混合的基于 ADN 的单组元推进剂表现出与 LMP-103S 相似的爆炸力。此外,与四甘醇二甲醚混合的推进剂的理论真空比冲比与其他燃料的推进剂相比高 1-6%。总体而言,与四甘醇二甲醚混合的 ADN 水溶液可能是卫星应用的有前途的燃料候选者之一。TGA-DSC分析表明,对于推进剂的预热温度,催化剂活性材料是比燃料的闪点和自燃温度更重要的因素。与四甘醇二甲醚混合的基于 ADN 的单组元推进剂表现出与 LMP-103S 相似的爆炸力。此外,与四甘醇二甲醚混合的推进剂的理论真空比冲比与其他燃料的推进剂相比高 1-6%。总体而言,与四甘醇二甲醚混合的 ADN 水溶液可能是卫星应用的有前途的燃料候选者之一。TGA-DSC分析表明,对于推进剂的预热温度,催化剂活性材料是比燃料的闪点和自燃温度更重要的因素。与四甘醇二甲醚混合的基于 ADN 的单组元推进剂表现出与 LMP-103S 相似的爆炸力。此外,与四甘醇二甲醚混合的推进剂的理论真空比冲比与其他燃料的推进剂相比高 1-6%。总体而言,与四甘醇二甲醚混合的 ADN 水溶液可能是卫星应用的有前途的燃料候选者之一。此外,与四甘醇二甲醚混合的推进剂的理论真空比冲比与其他燃料的推进剂相比高 1-6%。总体而言,与四甘醇二甲醚混合的 ADN 水溶液可能是卫星应用的有前途的燃料候选者之一。此外,与四甘醇二甲醚混合的推进剂的理论真空比冲比与其他燃料的推进剂相比高 1-6%。总体而言,与四甘醇二甲醚混合的 ADN 水溶液可能是卫星应用的有前途的燃料候选者之一。
