General Electric Co. and Safran SA are teaming up to develop technologies for a new generation of jet engines, seeking a breakthrough that would cut fuel consumption by more than 20% and potentially power single-aisle planes by the middle of next decade.
The demonstration program will focus on a so-called open fan architecture, in which the engine’s blades operate without a traditional casing, as well as other techniques to boost efficiency. The longtime joint-venture partners in CFM International Inc. will also pursue hybrid-electric technology and make the engine fully compatible with sustainable aviation fuels and hydrogen.
