Abstract

To improve secondary combustion efficiency of solid rocket ramjet, the method of introducing high temperature gas injection into front end of combustor to enhance mixture and combustion was proposed in this paper. Also, numerical simulation and test were conducted to study feasibility of the method. The simulation results show that the introduction of gas injection could increase temperature in front part of combustor, thereby facilitating combustion of propellant and improving combustion efficiency of solid rocket ramjet. Besides, the method was validated by test data that indicated rise of secondary combustion efficiency from 81.3% to 88.7%.

Key words： gas injection; solid rocket ramjet; combustion efficiency; fuel rich propellant
