Abstract

This paper describes the development and construction of an energy harvesting device to provide a safe, reliable source of electrical energy onboard gravity-dropped weapons such as aerial bombs. The generators collect and store mechanical energy as the weapon falls away from the aircraft. Only after the weapon has fallen away from the aircraft is the stored mechanical energy released, generating electricity through a hybrid piezoelectric and electromagnetic generation method. The design, construction, and testing of the generator is discussed at length. Conceptual designs for integrating the described energy harvester alongside current and alternative sources of electrical power are also discussed.
