Promising Electric Aircraft Drive Systems (Future of Electric Vehicles USA 2010)

An overview of electric aircraft propulsion technology performance thresholds for key power system components is presented. A weight comparison of electric drive systems normalized by total delivered energy is made to help identify component performance requirements, and promising research and development opportunities.

Michael Dudley is the Flight Vehicle R&T Div Chief at NASA Ames Research Center, leading the Center's Systems Analysis and Integration function; and Advanced Rotorcraft Technology Development. During 31 years with NASA he has served in both project and line management, and performed research in powered-lift, and aerodynamic prediction codes. He has a Cal Poly Aero Eng BS, a Stanford Mech Eng MS, and a MBA from MIT. He is an AIAA Associate Fellow, and a pilot for 40 years.

NASA's reach spans the universe. The rover Opportunity is still studying Mars after arriving with its twin Spirit in 2004. Cassini orbits around Saturn, as Juno makes its way to Jupiter. The Hubble Space Telescope continues to explore the deepest reaches of the cosmos. The crew of the International Space Station is extending the permanent human presence in space. Earth Science satellites are sending unprecedented data on Earth's oceans, climate and other features. NASA's aeronautics team is working with other government organizations, universities, and industry to fundamentally improve the air transportation experience and retain our nation's leadership in global aviation.
