Most regional airline flights last about an hour, and today’s aircraft rely on engines that work hardest during takeoff and climb.
The RTX Hybrid-Electric Flight Demonstrator explores a new approach, combining an electric motor with a thermal engine in a parallel hybrid-electric propulsion system.
By sharing power between electric and thermal sources across different phases of flight, hybrid architectures open new opportunities for efficiency. Over a one-hour mission, this approach could reduce fuel burn by up to 30% compared to today’s regional turboprops, with the potential for even greater gains through in-flight energy recovery.
Watch to learn how hybrid-electric propulsion could reshape regional aviation.
