NASA's Magnetic Gearing Research for Electrified Aircraft PropulsionThis paper presents an overview of the magnetic gearing research being conducted at NASA. First, the research is motivated through an in-depth discussion of the Agency-level aeronautics vision, the benefit of geared drivetrains, the barriers to applying mechanical gears in future aircraft concepts with electrified aircraft propulsion, and the characteristics of magnetic gears that allow them to overcome said barriers. Next, the principles of operation and current limitations of magnetic gears are discussed in the context of future electrified aircraft. Then, the authors' vision for the magnetic gearing research that will be needed to enable the next generation of electrified aircraft is presented. Lastly, the recent and ongoing magnetic gearing research at NASA is described, with a focus on the development and capabilities of a new rotating test rig and new static measurements of an in-house prototype. Results and lessons learned thus far are summarized.
