Hybridized Propulsion Advances Toward Airbus Technology Downselect

July 23, 2026 - 07:05

A major step toward cleaner air travel is unfolding as Collins Aerospace and Safran push forward with testing of electric powertrains designed for hybridized turbine engines. The two companies, already partners in the engine joint venture CFM International, are now focusing on a technology that could fundamentally change how aircraft generate and use power.

The current testing phase involves high-voltage electric motors and generators that can be integrated into a conventional gas turbine. The idea is not to replace the jet engine entirely but to create a hybrid system where electric power assists during takeoff and climb, reducing fuel burn and emissions. During cruise, the turbine would recharge the batteries or power the electric components directly.

This work is part of a broader push toward a technology downselect, where Airbus will choose which hybrid-electric architectures to pursue for future aircraft programs. The European planemaker has set ambitious targets for decarbonization, and hybrid propulsion is seen as a critical bridge between today's engines and full electric flight.

Collins and Safran are testing components at multiple facilities, including high-altitude chambers that simulate flight conditions. Engineers are measuring efficiency, thermal management, and power density. The goal is to prove that the added weight of electric systems does not cancel out the fuel savings.

If successful, the hybridized turbine could enter service in the 2030s on narrowbody aircraft, the workhorses of global aviation. For now, the tests remain in the lab, but the results will shape Airbus's next generation of airliners.
