Track: Energy & Resilience
Area: Transportation
Tech Readiness: TRL 2

Tech Brief: Very high magnetic fields driven through air (as opposed to ferromagnetic iron in conventional machines) is used to increase the power to weight ratio of electrical machines by an order-of-magnitude, enabling electric propulsion of aircraft and making large amounts of electrical power available for advanced weapon systems in air.


Value Proposition: If successful and risks reduced, this can enable distributed/hybrid electric propulsion and help manage thermal challenges in the next generation of DOD aircraft, and in the long term help transition to Low-Carbon Propulsion in conjunction with fuel cells/energy storage when their power density improves. It can also help increase the power density and efficiency of actuators enabling improved Unmanned Aircraft Systems with smarter, more electric systems. The technology could also benefit other applications that require lightweight machines like ship propulsion and land vehicles that need electric power.
