ABSTRACT:
A self consumable initiator is comprised of a consumable material selected from pyrotechnics, propellants, exothermic alloys, and primary explosive compositions, and one or more lengths of a fiber optic material in physical contact with or embedded in the consumable material. Uniform density of laser energy is transmitted through the fiber optic material to the consumable material in sufficient amount to stimulate the consumable material to its respective ignition point. The consumable material self consumes as it serves to ignite a larger quantity of material such a solid propellant grain. The consumable material is in the form of pellets powders, or castable shapes. When installed in a rocket motor case, the self consumable initiator is bonded or installed as a castable pyrotechnic which conforms to the contour of the front end of a solid rocket motor case. Subsequently, a solid propellant grain is bonded or cast in place in intimate contact with the initiator. After being stimulated to its ignition point with laser energy the consumable material serves to ignite the solid propellant grain.
