NASA and GE Aerospace demonstrate hybrid-electric flight

NASA and GE Aerospace have successfully demonstrated a megawatt-class hybrid-electric aircraft engine in flight, marking a significant step toward more fuel-efficient aviation. The engine, mounted on a Saab 340B aircraft, made its public debut at the Farnborough International Air Show in the United Kingdom. This system has already set records, becoming the first hybrid-electric aircraft to fly above 30,000 feet and completing the longest hybrid-electric flight of over two hours.

The technology integrates electric motors, a gas turbine, and energy storage, and is designed to power regional-class jets while reducing fuel burn and operating costs. The demonstration flight is the result of more than 15 years of research, including work under NASA’s former Electrified Powertrain Flight Demonstration project and the ongoing Subsonic Vehicle Technologies and Tools project. Key testing took place at NASA’s Electric Aircraft Testbed at the Neil A. Armstrong Test Facility in Sandusky, Ohio, where the system was tested at simulated altitudes of 45,000 feet.

Laurie Grindle, director of the Aeronautics Division at NASA Headquarters, said the achievement reflects NASA’s role in exploring bold possibilities and working with industry to turn breakthroughs into real-world technologies. Ralph Jansen, an aerospace engineer at NASA’s Glenn Research Center, noted that the project involved hundreds of people across NASA centers and partner companies, including GE Aerospace, BETA Technologies, and Boeing.

The success validates years of NASA research that began when hybrid-electric propulsion for large aircraft seemed nearly impossible. The agency spent about seven years on preliminary research, addressing barriers such as power, thermal, and battery technology, as well as system integration. The next steps involve using the demonstrated technology and designs to develop future hybrid systems that could lower airline operating costs and reduce energy use in aviation.
