Airbus Racer Compound Helicopter Flies at the Paris Air Show – AIN

Powered by two Safran Aneto-1X turboshaft engines, Racer is designed to fly at more than 215 knots while burning about 20% less fuel compared with current-generation helicopters. Racer is part of the European Clean Sky 2 research program and involves 40 partners in 13 countries.

The rotorcraft features a double-wing design with lateral pusher rotors on each wingtip. In cruise flight, Safran’s Eco-Mode hybrid-electric system allows one of the two engines to be switched to standby mode, according to Airbus, “generating further fuel savings of up to 30%.”

Airbus validated the aerodynamic configuration of Racer with research on its X3 technology demonstrator, which combined fixed wings with lateral rotors and a main rotor system. In 2013, the demonstrator broke the helicopter speed record when it flew at 255 knots.
