The Racer
An aerodynamic configuration at the service of high speed
The Racer builds upon the success of Airbus Helicopters' X3 demonstrator, which validated an aerodynamic configuration that combines a traditional main rotor and innovative lateral rotors.
Optimised for a cruise speed of 400 km/h, the Racer features a variety of innovative technologies, including:
- A characteristic box-wing designed for aerodynamic efficiency
- A hybrid metallic-composite airframe designed for low weight
- A new high-voltage, direct-current electric generator
- A rear fuselage with an asymmetric cross-section profile, designed to optimise hover performances without penalising the forward and cruise flight phases
The Racer demonstrator – developed as part of the European Clean Sky 2 research programme – has an optimal blend of high performance and reduced operating costs.
Improving the environmental and acoustic performance of helicopters is a key focus area of the Racer demonstrator programme. The dynamic configuration enables 15% less fuel burn per nautical mile at 180 kts compared to a conventional helicopter at 130 kts. The innovative Safran Eco-Mode hybrid-electric system – which allows one of the two Aneto-1X engines to be switched to stand-by while in cruise flight – generates further fuel savings of up to 30%. The distinct architecture of the Racer formula also contributes to lowering its operational acoustic footprint.
Developed as part of the European Research Clean Sky 2 project, the Racer pulls together the skills and know-how of 40 partners in 13 European countries.
The Racer intends to demonstrate the advantages of high speed for a wide range of missions. These missions include the following:
- Emergency medical services (where the greatest chance of saving lives depends on help arriving within the first “golden hour”)
- Search and rescue operations
- Public service
- Commercial transportation
