NASA and GE Aerospace Pioneering Hybrid-Electric Jet Engines for a Greener Future

A New Era of Aviation Technology

NASA and GE Aerospace are working together to design a hybrid-electric jet engine that will revolutionize air travel. Like hybrid cars, this engine will combine fuel-burning and electric power to drastically reduce fuel usage. This development could propel the aviation industry into a more sustainable future.

How Does a Hybrid-Electric Jet Engine Work?

In this engine, a fuel-burning core powers the jet, with electric motors providing additional thrust. These motors generate electric power, which feeds back into the engine to reduce fuel consumption. Essentially, this system lowers fuel burn without sacrificing performance.

The project, known as HyTEC (Hybrid Thermally Efficient Core), aims to bring hybrid-electric jet engines to commercial use by the 2030s. This is the first time a mild hybrid-electric engine could be used for airliners.

A Leap Toward Sustainable Aviation

The HyTEC project is about more than just developing a hybrid engine. NASA and GE are also focusing on creating a smaller engine core that produces as much thrust as today's larger engines. This would not only reduce fuel burn by 5-10% but also lower emissions, moving aviation closer to sustainability.

What Sets This Engine Apart?

Traditional jet engines have onboard generators, but they don't help power the engine itself. The HyTEC project changes this by integrating electric motor-generators directly into the engine. These motors optimize engine performance during different phases of flight, providing maximum fuel efficiency. This approach speeds up the development of hybrid-electric aviation technology, even before battery storage systems fully mature.

The Future of Hybrid-Electric Air Travel

GE Aerospace’s Passport engine is currently undergoing modifications for hybrid-electric testing. Researchers are testing the best phases of flight to maximize fuel savings. This innovative engine could make hybrid-electric airliners a reality within the next decade.

The HyTEC project is part of NASA's broader Sustainable Flight National Partnership, which aims to achieve net-zero greenhouse gas emissions in aviation by 2050. This collaboration between industry, government, and academia is an essential step toward creating a more sustainable aviation industry.
