Abstract

In order to research the law of propellant combustion and output pressure during the working process of the solid rocket motor igniter, a numerical calculation study is carried out on the combustion process of a certain igniter in a closed pressure measuring vessel by establishing a mathematical model of the ignition powder combustion of the igniter. The combustion law of the ignition powder in the igniter and the pressure distribution law in the pressure measuring vessel during the combustion process are analyzed. The calculated P-t curve is in good agreement with the test results, indicating that the established ignition powder combustion model and calculation method are reasonable and correct.

Key words： solid rocket motor; ignition; gunpowder combustion; numerical analysis
