摘要
采用靶线法在3.0～15.0MPa压强范围内,研究了固含量、铝粉含量、二硝酰胺铵(ADN)的粒径及含量、燃速调节剂及热稳定剂对PGN/ADN推进剂燃烧性能的影响。结果表明,ADN的粒径(<450μm,450～900μm)和含量(0%～30%)增加时,PGN/ADN推进剂的燃速和压强指数均适当增加;改变Al粉含量,PGN/ADN推进剂的燃速和压强指数均无明显变化;添加适量(0.5%)燃速调节剂Fe2O3可增加推进剂的燃速并降低压强指数,添加适量(0.5%)燃速调节剂草酰胺可有效降低压强指数。添加适量稳定剂(1%)2-硝基二苯胺(2-DNPA)和N-甲基-4-硝基苯胺(MNA)可以使推进剂的压强指数分别由0.49降低到0.34和0.40。
By using the target-line method,the effects of solid content,aluminum content,ammonium dinitramide（ADN） content and particle size,burning rate catalyst and heat stabilizer on the combustion properties of PGN/ADN propellants were studied during the pressure from 3.0 MPa to 15.0 MPa.Results show that the burning rate of PGN/ADN propellants increases from 9.63 mm·s-1 to 26.71 mm·s-1,of which the pressure exponent increases from 0.49 to 1.05 when the diameter of ADN increases from less than 450 μm to 450-900 μm.On the other hand,the burning rate increases from 4.83 mm·s-1 to 12.18 mm·s-1,and the pressure exponent increases from 0.11 to 0.61 when the content of ADN increases from 0 to 30%.Aluminum had little effect on buring rate and pressure exponent.Burning rate increases 16.1% by adding Fe2O3 with 0.5% content.The pressure exponent drops to 0.22 by adding oxamide（OXM） with the same content as Fe2O3;simultaneously,the pressure exponent drops differently to 0.34 and 0.40 by adding 1% 2-nitrodiphenylamine（2-DNPA） and 1% N-methyl-4-nitroaniline（MNA） stabilizer separately.
