Abstract
In order to improve the combustion properties of HTPB propellants,the effect of carbonate composites,ferrocene derivative G,high-nitrogen energetic material M,nanometer metal oxide particles and nano-aluminum on combustion characteristics of HTPB propellants was studied.The results show that carbonate composites decreased the burning rate and pressure exponent of HTPB propellants.The ferrocene derivative G decreased the pressure exponent of HTPB propellants to 0.27 in the pressure range of 8.60-17.12MPa,and increased their burning rate.High-nitrogen energetic material M decreased both the burning rate and the pressure exponent of HTPB propellants.Modifier M and G decreased the pressure exponent of HTPB propellants to 0.24 in the pressure range of 8.63-16.48MPa.Nano aluminum and nano-metal oxide obviously decreased the pressure exponent of HTPB propellants.
