Abstract
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.关键词
