SABRE (Shape Adaptive Blades for Rotorcraft Efficiency): a project to reduce helicopter emissions

The video explores the necessity for, and the importance of this hugely successful EU sponsored morphing rotorcraft blade engineering project.

A four-year, multidisciplinary research programme sponsored by the EU Horizon 2020 Programme.
Helicopters provide life-saving and logistical services. Until now, the complex physics that underlies rotor blade design has limited aerodynamic improvements to their fixed blades. By developing blades that can morph and change shape to adapt to changing operating conditions, the team hopes to realise significant reduction in fuel burn and emissions. Analysis indicates emissions may be reduced by up to 10 per cent by incorporating multiple morphing concepts into a single blade. These devices may even reduce the noise generated by the rotor.

The researchers have been sharing their enthusiasm for greener aviation technologies at a number of outreach events, summer schools and festivals. They are also exploring potential use in commercial aircraft, wind turbines and electric air vehicles.
