Developed with Rolls-Royce, E-Thrust is an Airbus concept for a future airliner with hybrid-electric distributed propulsion for reduced fuel consumption and emissions.
With the increasing of the rotational speed, the water film pressure and the load capacity of the elastic-metal-plastic thrust bearing were reduced by 50%.
