Racer Model Overview

A pioneering high-speed helicopter created by Airbus Helicopters for the European Clean Sky 2 research program is the RACER (Rapid and Cost-Effective Rotorcraft). This program aims to revolutionize rotorcraft technology by combining helicopter efficiency with fixed-wing aircraft speed. The RACER attempts to improve mission efficiency and operational reach by increasing speed. One of the fastest rotorcraft under development, it can reach 400 km/h (250 mph). This speed is achieved by combining a main rotor with lateral pusher propellers to optimize lift and propulsion beyond standard helicopter performance.
The RACER shows Airbus Helicopters’ sustainability and innovation. Its sophisticated aerodynamics and lightweight materials boost fuel economy and lessen environmental impact. Box wings increase the lift-to-drag ratio and reduce noise, making aircraft quieter and greener. Advanced fly-by-wire technologies improve safety and control. The RACER’s advanced avionics push rotorcraft capabilities. Airbus Helicopters wants to reduce high-speed air travel’s carbon impact by using sustainable materials and fuels. RACER exhibits technical advances and supports Airbus’s sustainable aviation ambitions.
A Successful Recipe
The “compound” formula of the aircraft, which has been successfully tested on the X3 demonstrator since 2010, is the key to this achievement. The Racer’s unique construction, which includes propulsive propellers, a fixed wing, a helicopter rotor, and unusual fuselage aerodynamics, is combined with cutting-edge engine power management and an autopilot that is skilled at maximizing this combination. “The Eco-Mode system, which was created with assistance from the French Civil Aviation Authority (DGAC) and multiple other partners, is crucial in achieving the desired results,” highlights Julien Guitton.
During cruise flight, one of the two engines is placed on standby, and if needed, it may be nearly instantly restarted. The aircraft is nevertheless quicker than a traditional helicopter, even if it travels a little bit more slowly than it would if both engines were working. Most importantly, it reduces fuel usage by 20%. By using flaps on the trailing edge, the wing’s performance is also maximized throughout the flight, which helps to reduce fuel consumption. The wing relieves the rotor of 40% of the overall lift, lowering dynamic loads and vibrations. Additionally, the Racer claims to be more comfortable than a traditional helicopter.

Julien Guitton says, “We can fully utilize all the opportunities provided by the compound formula because of the flight control system and autopilot.” He gives the following example: “We can change the aircraft’s location and execute previously unheard-of low-noise approaches by varying the power distribution among the rotors.” Longer maintenance intervals are among the anticipated additional advantages. According to our interactions, one of the biggest challenges for this initiative is proving that we can verify technological solutions with extended operational life cycles.
Key features:
The RACER has a hybrid design, with a main rotor and lateral pusher propellers. This combination enables it to go faster than ordinary helicopters.
- Speed: – The RACER hopes to attain speeds of up to 400 km/h (250 mph), which is much quicker than conventional helicopters.
- economy: The design uses modern aerodynamics and lightweight materials to improve fuel economy and minimize environmental impact.
- Sustainability: Airbus Helicopters aims to reduce the carbon footprint of the RACER by employing sustainable materials and alternative fuels.
- Innovative technology: The RACER uses cutting-edge technology, such as a box-wing design, to enhance lift-to-drag ratio and minimize noise levels. Advanced fly-by-wire technologies provide improved control and safety.
Design and Development
- Structure: The RACER’s composite fuselage decreases weight and increases durability and stress resistance. Composite materials increase performance, fuel economy, and operating costs. Aerodynamic innovations like the box-wing configuration increase lift and efficiency. The RACER can fly faster and more maneuverably than typical helicopters due to its stability and reduced drag.
- Propulsion: Two high-performance, fuel-efficient Safran Arrano turboshaft engines power the RACER. These engines power the RACER’s main rotor and lateral pusher propellers to its goal speeds. Dual engines provide redundancy and dependability, which are essential for high-speed flying safety. These engines and the RACER’s hybrid propulsion system provide it with outstanding speed and helicopter adaptability.
- Avionics: Advanced avionics systems on the RACER improve situational awareness and safety with great automation. These systems use cutting-edge navigation, communication, and control technology to improve aircraft operations and reduce pilot burden.

Because of its efficiency, the RACER promotes intercity travel by strengthening connections between metropolitan areas and offering a quicker option than conventional ground transportation.
- Impact on the Environment: When developing the RACER, Airbus Helicopters gave environmental sustainability top priority. Because of its sophisticated design, the aircraft consumes less fuel overall and has reduced operating expenses because of its improved fuel economy. Moreover, one of the main environmental issues with rotorcraft operations is noise, and the RACER’s design incorporates elements to minimize noise levels. Through its alignment with Airbus’s wider sustainability objectives, the RACER helps to lessen the environmental impact of high-speed aviation.
- Market Growth: High-speed rotorcraft now have more business potential thanks to the RACER. The RACER’s revolutionary design and performance characteristics position it to satisfy the growing need for quicker and more efficient air transport options.
