An international team led by Airbus Helicopters (AH) is working on the technology to achieve these goals with the RACER demonstrator. Scientists from the Technical University of Munich (TUM) have designed an aerodynamically shape-optimized rotor head full fairing for the innovative RACER rotorcraft. The fairing will reduce energy consumption and make higher speeds possible. Vertical take-off and landing aircraft are essential whenever there's not enough room for runways, for example in mountain rescue missions, flights to oil platforms or when providing medical services to remote areas. But conventional helicopters consume more energy and achieve lower speeds in forward flight than fixed-wing aircraft.
