Abstract
A rocket motor having a desensitizing mechanism for preventing explosion or violent reaction during slow cook-off is provided. The rocket motor includes a case contained rocket propellant with a desensitizing assembly attached forward of the propellant charge. The desensitizing assembly is formed with an enclosure containing a desensitizing fluid, and connected to the interior of the rocket motor by a tube which is sealed by a heat sensitive plug. The heat sensitive plug melts at a temperature below the slow cook-off temperature of the rocket propellant. The melting of the plug allows the desensitizing fluid to be ejected into the interior of the casing and onto the propellant charges, thereby, desensitizing the propellant charge.
