Doing More with Less – BLI on a Big Scale

Hybrid and electric cars sell because they lower operating costs for the owner.  Designers and manufacturers sort out ways to increase efficiency, including streamlining, using low-rolling-resistance tires, and making structures lighter.  An added technology, boundary layer ingestion (BLI) may add to aircraft efficiency. NASA and industry leaders are working on equivalent solutions for aircraft, and airplanes will end up as different from today’s designs as Toyota Priuses and BMW i3s are from Ford Falcons or Chevrolet Corvettes.  NASA proclaims, “An aviation renaissance, one focused on energy efficiency and economic impact, is on the horizon, and it’s changing how engineers look at aircraft power and design.” Jim Heidmann, a manager of NASA’s Advanced Air Transport Technology Project (AATT), says, “I feel we …

Electric Jet Hybrids – Big and Small

NASA’s Glenn Research Center reviews the prevalence of fossil fuels in keeping us flying for over a century. “Since the beginning, commercial planes have been powered by carbon-based fuels such as gasoline or kerosene. While these provide the energy to lift large commercial jets into the world’s airspace, electric power is now seen as a new frontier for providing thrust and power for flight.” Noting the use of hybrid and turboelectric power used to increase efficiency in cars, boats and trains, NASA has set a goal “to help the aircraft industry shift from relying solely on gas turbines to using hybrid electric and turboelectric propulsion in order to reduce energy consumption, emissions and noise.” This would require a large shift …

Dr. Ajay Misra Leads Off With a Hit at EAS VIII

Not to indulge in hyperbole, but people who missed the eighth annual Electric Aircraft Symposium will, like the laggards mentioned in Henry V’s speech, “think themselves accurs’d they were not here”  (Shakespeare, Henry V, act 4, scene III). After the Friday morning introductions by Dr. Brien Seeley, founder and president of the CAFE Foundation, things immediately went into high gear with the presentation by Dr. Ajay Misra, NASA Glenn Research Center.  A member of the Senior Executive Service, he is Chief of the Structures and Materials Division in the Research & Technology Directorate.  In this position, Dr. Misra has the responsibility for planning, advocating, coordinating, organizing, directing and supervising all phases of Division research and business activities. His degrees in …

Dr. Shin to Keynote Electric Aircraft Symposium

Dr. Jaiwon Shin, NASA Associate Administrator for Aeronautics, will close the Friday, April 25 session of the eighth annual Electric Aircraft Symposium with his keynote address, “The NASA Aeronautics Vision and Strategy – How It Relates to Electric Aircraft.”  As Associate Administrator, Dr. Shin “manages the agency’s aeronautics research portfolio and guides its strategic direction,” according to his official NASA biography.  He co-chairs the National Science & Technology Council’s Aeronautics Science & Technology Subcommittee, a group of federal departments and agencies that fund aeronautics-related research. Its first presidential policy for aeronautics research and development (R&D) was ratified by Executive Order 13419 in December 2006, and now guides such research until 2020.  Dr. Shin oversees and sets policies for an array …
