Study on Thermal Safety of Hydroxylamine Nitrate Based Liquid Propellants
摘要
Abstract
In order to evaluate the safety of hydroxylamine nitrate(HAN)based liquid propellants in production,storage,transportation and use,thermal decomposition process of the propellant was studied using a differential scanning calorimeter(DSC),and thermal safety parameters were also calculated.Changes of impact energy with temperature were tested by a BAM impact sensitivity tester.The results show that the apparent activation energies obtained by K-A-S,F-W-O,and Starink methods are 154.8,154.6 kJ/mol and 155.6 kJ/mol,respectively.Thermal decomposition free energy,activation enthalpy,and activation entropy are 128.2,150.9 kJ/mol and 48.9 J/mol,respectively.Critical temperature of thermal explosion is204.2℃,and adiabatic time to explosion is about3.92-55.52 s.Using AKTS software,the tempera-ture corresponding to the induction period of 2,4,8 h and24 h is123.4,119.1,114.8℃ and 108.2℃,respectively.The self-accelerating decomposition temperature of packaging weights of 0.01,5.00,25.00,50.00 kg and 100.00 kg are 116,104,103,102℃and 101℃,respectively.Critical impact energies at different temperatures are>50(25℃),40(80℃),25(90℃),10 J(100℃) and 5 J(110℃).It is necessary to avoid high temperature caused by collision during the production,storage,and transportation of HAN based liquid propellants.关键词
