Airplanes of the future may be powered by hybrid-electric engines, NASA engineers working to keep the skies free of fossil fuels say. NASA is presenting the current state of its propulsion research at the 2016 SciTech conference of the American Institute of Aeronautics and Astronautics, currently taking place in San Diego, California. Project engineers and researchers at the Glenn Research Center in Cleveland, Ohio are looking at electrical systems that could either replace or complement the current turbine engines, turning electricity into thrust. Switching to a new type of propulsion is not going to be simple, however. NASA engineers hope to eventually increase fuel efficiency by as much as 30 percent.
