Combustion Properties of PGN/ADN Propellants

SHANG Dong-qin,HUANG Hong-yong(Shanghai Aerospace Chemical Engineering Institute,Huzhou 313000,China)  
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.
