Hybrid propulsion system including a chemically rechargeable ultra-capacitor

Abstract:

An aeronautical propulsion system includes a fan having a plurality of fan blades and an electric motor drivingly connected to the fan for rotating the plurality of fan blades. A chemically rechargeable ultra-capacitor is included for providing the electric motor with a substantially continuous flow of electric energy during operation of the chemically rechargeable ultra-capacitor, resulting in a more efficient aeronautical propulsion system.
