Present Capability of Ram Air-Driven Alternators Developed at HDL as Fuze Power Supplies

Abstract

Harry Diamond Laboratories (HDL) has developed an air-driven alternator as a low-cost, easily manufacturable power supply for the M734 multi- option fuze for mortars (750,000 have been produced to date). As a result of this program, HDL has acquired the technical capability of producing alternators of similar design to meet a wide range of fuze power requirements for other mortar, bomb, and artillery applications. Design features of alternators for these applications are discussed. These include methods of achieving velocity discrimination, enhancing bearing life by limiting shaft rotational speed at high projectile velocities, increasing power output with high-energy samarium- cobalt magnets, and strengthening the design for artillery environment.
