REVIEW OF PATENT LITERATURE ON ELONGATED IGNITION SYSTEMS WITH COMBUSTIBLE TUBES FOR FIXED ARTILLERY AMMUNITION

Abstract

The paper dwells on studies of foreign patent literature on design solutions for elongated systems of central ignition with combustible tubes containing the igniting stuff which stick out above the base of case and are used in fixed artillery rounds especially for tanks. The systems secure the ignition of propulsion charges within overall capacity of the case. Deployment of combustible tubes increases the level of safety as after firing with such ammunition the cartridge propulsion system leaves some incombustible parts of an elongated ignition system embedded into a case base which are removed from the cartridge chamber into a special container inside the combat vehicle. The lack of any hot protruding parts of the ignition system significantly reduces the risk of scorch injuries for the combat vehicle crew. Moreover the case bases without protruding parts need less room in the combat vehicle than the identical case bases with the protruding, usually steel, components of the elongated ignition system left after the firing.
