High-Speed Airbus Breaks Past 400 kilometers per hour Mark

The Airbus Racer (Rapid And Cost-Effective Rotorcraft) is a high-speed helicopter demonstrator, designed to revolutionize the helicopter industry by achieving significant advancements in speed, fuel efficiency, and noise reduction. The Racer has already made impressive strides, reaching speeds of 420 km/h (227 kts) during flight testing[1].

Performance Targets and Innovative Design

Racer aims for a top cruise speed of approximately 400 km/h (about 250 mph), which is roughly 30% faster than current conventional helicopters like the EC135, which cruises at about 254 km/h[2]. This speed is made possible by the Racer's advanced aerodynamic design and a compound helicopter configuration with a rigid main rotor and a pusher propeller, enabling high-speed flight.

Fuel Consumption Reduction and Eco-Mode

The Racer targets a 30% reduction in fuel consumption compared to comparable helicopters, improving operational efficiency and reducing emissions. This fuel efficiency is achieved through a hybrid propulsion system that combines turboshaft engines with an electrical transmission and optimized aerodynamics[3]. The Racer's eco-mode propulsion system, developed in collaboration with Safran Helicopter Engines, allows one of the two Aneto-1X engines to be paused during cruise flight[4].

Acoustic Footprint and Noise Reduction

One of Racer’s key innovations is a significantly reduced noise signature, approximately 50% less acoustic footprint than traditional helicopters, through quieter rotor designs and active noise reduction technologies[5]. This makes it better suited for urban air mobility and sensitive environment operations.

Future Plans and Collaboration

Airbus intends to complete the technology demonstrator development and flight testing phases through the mid-2020s to validate the advanced technologies. Success with Racer will inform commercial high-speed rotorcraft designs for civil and military markets expected to emerge in the 2030s[6]. The Racer demonstrator is a product of the European Research Clean Sky 2 project, involving 40 partners in 13 European countries[7].

The Racer's Next Phase of Flight Testing

The next phase of flight testing for the Racer demonstrator will focus on single engine operations and finalizing the flight envelope[8]. This phase will also include an eco-mode, which allows for one engine to be shut down in forward flight, reducing fuel consumption and lowering CO2 emissions[9]. Bruno Even, CEO of Airbus Helicopters, stated that the aircraft's aerodynamic behavior and stability are promising[10].
