Here's one for #technologyTuesday! In an effort to improve fuel efficiency, NASA and the aircraft industry are rethinking aircraft design. Inside the 8’ x 6’ wind tunnel at NASA Glenn, engineers recently tested a fan and inlet design, commonly called a propulsor, which could use four to eight percent less fuel than today’s advanced aircraft. It is designed to be embedded in the aircraft’s body, where it would ingest the slower flowing air that normally develops along an aircraft’s surface, called boundary layer, and use it to help propel the aircraft.
