Hybrid Propulsion Takes Step Forward In Commercial Aviation
GE Aerospace has successfully completed ground testing of a hybrid electric turbofan engine system, marking a crucial step toward bringing electric propulsion into mainstream commercial aviation. The tests, conducted under a NASA-supported research effort, demonstrated the ability to extract power from the engine and inject it back into the propulsion system while maintaining stable operation. The results met or exceeded technical benchmarks established by NASA, including targets tied to fuel efficiency and power requirements for future single-aisle aircraft. This milestone is part of CFM International’s RISE technology program, which aims to reduce fuel burn by more than 20% compared with today’s in-service engines. The testing was first reported by AeroTime.
