Abstract

High energy particles are added in solid ramjet propellant in order to enhance specific pulse. It is argued the effect of particles on insulator in heat transfer and impingement erosion. The particle in this paper is aluminum particle. The particles of two different diameters were argued in this paper. The result shows that heat transfer has been enforced in inlet-downstream area, and large particles make more heat transfer. Lots of particles break up while impinging on the insulator. Carbon particles generated by incomplete propellant burning performs little effect on insulator ablation.

Key words： insulator; ramjet particle; erosion
