Abstract: A consumable igniter for a solid rocket motor comprises a substantially spherical reinforced thin case (111) and a combustible charge, in the form of a layer (112), lining the internal surface of the case, with the combustible charge and the case defining a combustion chamber (113). A plurality of through-holes are formed in the case defining respective sonic throats. At least one small container (120) is received in one of the through-holes and projects inwardly toward the combustion chamber (113), the container containing a charge (121) for igniting the combustible charge layer (112) of the igniter (110). An ignition device (125) penetrates into the small container for igniting the charge contained within the small container.
