Airbus, Rolls-Royce and Siemens have come together to develop a hybrid electric engine as the race intensifies to advance battery technology and electric motors to lower flying costs and move away from fossil fuels.
Dubbed the E-Fan X program, the three companies anticipate flying a demonstrator aircraft in 2020 after ground tests, provisionally on a BAe 146 aircraft.
“We see hybrid-electric propulsion as a compelling technology for the future of aviation,” Airbus Chief Technology Officer Paul Eremenko said in a joint statement.
Airbus will be responsible for the control architecture of the hybrid-electric propulsion system and batteries, and its integration with flight controls. Rolls-Royce will be responsible for the turbo shaft engine and 2 megawatt generator, while Siemens will deliver the 2 MW electric motor.
In October, a Seattle-area startup – backed by the venture capital arms of Boeing Co and JetBlue Airways Corp – announced plans to bring a small hybrid-electric commuter aircraft to market by 2022.
