Engine Maker Completes High-Altitude Flight Using Hybrid-Electric Propulsion
GE Aerospace has successfully completed the world’s first high-altitude flight assisted by hybrid-electric propulsion, marking a major milestone in the development of more efficient and environmentally friendly aircraft engines. The flight, which took place above 30,000 feet, was made possible by a Saab 340 aircraft that has been modified to carry out similar trials since May. The research is being carried out in cooperation with NASA and electric aerospace company BETA Technologies, and was first reported by Reuters.
