This high-speed helicopter from Airbus flies fast over 400 km / h

It is a Formula 1 flier: the high-speed helicopter racer, presented by Airbus at the Paris aviation show, will race through the air at over 400 km / h.

The speed monster with double deck surfaces and extra propellers will stand out in 2020 for first rescue operations.

How fast is a classic rescue helicopter? The EC135 from Airbus Helicopters, used by the ADAC in air rescue, brings it to a traveling speed of 230 km / h.

That is fast.!

Airbus Helicopters is convinced, however, to make rescue operations even more efficient.

“Today, we present our vision of future high-speed helicopters,” said Guillaume Faury, CEO of Airbus Helicopters at the Paris Air Show in Le Bourget to present the concept for the racer a high-speed helicopter ,capable of traveling at over 400 km / Is designed.

The final assembly is scheduled to begin in 2019. The high-speed heli will be ready a year later for first rescue operations.

DLR has designed double deck surfaces

The heart of the helicopter is the so-called boxwing design: in addition to the classic main rotor, double deck surfaces provide additional buoyancy during the flight.

The German Aerospace Center (DLR) has been involved in the design of the wings.

The final design allows the racer to fly at full air speed, with low fuel consumption, “says Thorsten Schwarz from the DLR Institute for Aerodynamics and Flow Technology in Braunschweig.

“Our aerodynamic improvements for the rear boom have been focused on the elevator to ensure good maneuverability and stability of the helicopter combined with low air resistance.”

Two additional propellers are also mounted at the ends of the double deck surfaces which provide the necessary forward thrust for high speeds. The drive is powered by two RTM322 turbines from Rolls-Royce.

High-speed heli will hardly disturb residents

The racer will not only fly at record speeds. He will also be comparatively quiet. DLR engineers have analyzed the acoustic characteristics of the helicopter demonstrator for several flight conditions.

“The identified low noise emissions will help Airbus Helicopters and operators develop flight profiles with minimal noise impact on local residents,” says Schwarz.

But not only DLR contributes to the racer’s success. Experts from all over Europe are on board the research program.

“Within the scope of Clean Sky 2, dozens of European partners bring their knowledge and skills into this new, very daring project,” says Faury.

“We are thus setting new standards for the use of high-speed helicopters and are thus preparing the way for new time critical services by 2030 and beyond.”

That Racer actually stands out is, incidentally, very likely. The idea with additional wings and rotors has already proven itself in practice.

The company Eurocopter ,since 2013 Airbus Helicopters  had already broken a world record for helicopters in 2013: with the X3 flight screw, which brought it in a test flight to 472.
