The EU aviation industry is open to a novel idea that could save fuel and cut emissions
Annual global emissions from the international aerospace sector are already approximately 70 % higher than they were 15 years ago. The International Civil Aviation Organisation predicts they could increase by another 300 % by 2050 if measures are not taken. More efficient engines are one way to reduce emissions, and open rotor engines, under development since the 1980s, are gaining attention again. Characterised by two contra-rotating fans, open rotor architectures efficiently increase propulsion, thereby reducing fuel consumption and emissions. Controlling the angle of the blades has conventionally been achieved with hydraulic systems requiring extensive maintenance to prevent hydraulic fluid leakage. The EU-funded ROTATOR project is developing an electromechanical magnetic control system to further increase the reliability and cost-effectiveness of novel open rotor engines.
