摘　　要：研究了硝胺种类、固体组分含量和粒度、增塑剂与GAP的增塑比及燃速催化剂对GAP高能低特征信号推进剂在11~19MPa下燃烧性能的影响。结果表明,当HMX取代推进剂样品中的RDX时,推进剂的燃速较高,压强指数从0.72降至0.63;在AP和HMX总质量分数为67.5%的条件下,随着AP质量分数由5%增至30%,推进剂燃速逐渐增大,压强指数由0.82降至0.45;减小AP粒度以及在配方中添加燃速催化剂或调节过渡金属化合物J1/J2的配比,可较大幅度地增加推进剂燃速和降低压强指数,其中,J1与J2总质量分数为3%,二者质量比为2∶1和1∶1时,推进剂的压强指数较小,分别为0.50和0.48;随着HMX粒度减小及增塑剂与GAP黏合剂的增塑比的降低,推进剂的燃速和压强指数降低。The effects of nitramine variety,content and granularity of solid component,plasticizing ratio of plasticizer and GAP binders,and burning-rate catalysts on the combustion properties of GAP propellant with high energy and low signature under 11-19 MPa were studied.Results show that the burning rate of the propellant sample is higher and the pressure exponents decrease from 0.72 to 0.63 when HMX is substituted for RDX in the propellant samples.As the total mass fraction of AP and HMX is 67.5%,the burning rate increases gradually and the pressure exponent decreases from 0.82 to 0.45 with increasing the mass fraction of AP from 5%to 30%.Reducing the granularity of AP,adding the burning-rate catalysts and adjusting the ratios of transition metal compounds J1 and J2,can greatly increase the burning rate of the propellant and reduce the pressure exponent.In which,when the total mass fraction of J1 and J2 is 3% and the ratios of J1 and J2 are 2∶1 and 1∶1,the pressure exponents of the propellant are smaller,which are 0.50 and 0.48 respectively.With reducing the granularity of HMX and decreasing the plasticizing ratios of plasticizers and GAP binders,the burning rates and pressure exponents of the propellants reduce.
