For artillery and medium caliber munitions utilizing electronic fuze assemblies, numerous methods exist for collection or generation of the electrical energy required to power the fuze during flight. One general method of harvesting energy from the launch event is to employ the inertia of a movable generator component to effect a change in an electrically-coupled magnetic circuit. This paper describes methods of parameter selection and model-based design for the development of a switched-flux linear electric generator (LEG) of desired characteristics. Specifically, the tasks entailed development of a dynamic model for system-level simulation and the estimation of device flux and inductance profiles from finite element models for selected material characteristics. Single-magnet and dual-magnet designs, respectively capable of unipolar or bipolar flux operation were investigated. An experimental variant of the final dual-magnet LEG design was fabricated and analyzed. Recommendations for future design tasks are discussed. Also included is a brief overview of an inertial generator concept based on the angular acceleration of a magnetic rotor. A simple example of such a transverse-flux alternator is included and analyzed with discussion of the challenges facing further design.
