SYSTEM AND METHODS FOR PROPULSION AND POWERING SYSTEMS USING RECYCLABLE METALLIC FUELS

Provided are systems and methods for propulsion and powering systems using recyclable metallic fuels. The method includes capturing fuel products, including a metal oxide and unburnt fuel from combustion of a metallic fuel, storing the unburnt metallic fuel and the fuel products to generate power and/or thrust, and recycling the metal oxide to recreate the metallic fuel and/or byproducts. A system for propulsion and power generation using a metallic fuel includes a combustion chamber for combusting the metallic fuel to provide propulsion, a reaction chamber for generating electricity and thermal power using heat from unburnt metallic fuel and fuel products, a storage system for capturing the unburnt metallic fuel and the fuel products and at least one recycling system for directing the captured unburnt metallic fuel and/or the fuel products to the combustion chamber and/or the reaction chamber.
