Blue Edge is an advanced design of rotor blade developed and produced by multinational helicopter manufacturer Airbus Helicopters in cooperation with the French aerospace laboratory ONERA and the German Aerospace Center, purposed to achieve a meaningful reduction in both noise emissions and vibration as well as enhancement in aerodynamic efficiency for helicopters' operations.
Its existence was publicly revealed at the Heli-Expo 2010 in Houston, Texas. During 2014, Airbus Helicopters commenced flight testing of the Bluecopter Demonstrator, equipped with Blue Edge rotor blades amongst several other technologies. It has been incorporated onto several production helicopters, including the Airbus Helicopters H160 and the Airbus Helicopters H145.
