GE Aerospace Prepares First Flight Test for Hybrid-Electric Engine

Aviation is entering a new era as GE Aerospace recently completed successful ground testing of a megawatt-class hybrid-electric propulsion system.

Conducted at the company's Peebles Test Operation in Ohio, this milestone is part of NASA’s Electrified Powertrain Flight Demonstration (EPFD) program, which aims to revolutionize sustainable aviation for single-aisle aircraft.

The test involved integrating a GE CT7 gas turbine with advanced motor/generators, power converters, and batteries provided by BAE Systems.

During the evaluation, engineers simulated various flight stages, from taxiing to cruising, proving that the system can efficiently power propellers while simultaneously recharging onboard batteries.

This hybrid technology is a core element of the CFM International RISE program, designed to increase fuel efficiency by over 20% and lower CO2 emissions.

Looking ahead, GE Aerospace plans to transition from ground testing to flight demonstrations using a converted Saab 340B regional airliner.

By combining gas turbine performance with electric power, this innovation represents a significant leap toward a more sustainable future, with full compatibility for 100% Sustainable Aviation Fuel (SAF).

This achievement builds upon a decade of rigorous research, signaling that the next generation of cleaner, more efficient aircraft is quickly taking shape.
