Study on Measurement and Simplified Model of Burning Rate of AP/HTPB Base Bleed Propellant under High Pressure

Abstract:

In order to understand the burning rate of AP/HTPB propellant of the base bleed unit, the p-t curves of combustion of AP/HTPB base bleed propellant are measured in the closed bomb. The burning rate formula of the propellant under 50-200MPa is obtained by fitting to the experimental results. Based on division zone combustion theory, a simplified model of the burning rate of AP/HTPB base bleed propellant under high pressure is established. The calculation results and the experimental results are in good agreement.
