The process of solid fuel Alex combustion

This paper presents the combustion of a solid propellant formation with 15% ultra – fine aluminium powder called Alex. to evaluate the propellant burning results, a second comparable solid propellant was produced, containing 15% conventional aluminium yx76. The combustion experiments are performed in a high pressureclosed vessel at loading densities corresponding to pressures up to 280MPa for a given pressure, the burning rate of the Alex propellant is always higher than that of the YX76prpoellant. For each propellant, a vieille burning law is given. The burning rate pressure exponent of the Alex propellant is very low, as compared to that of the YX76 propellant.
