Airbus Unveils Half-Plane, Half-Copter In Quest For Speed

An anonymous reader quotes a report from The Verge: Airbus Helicopters showcased an experimental half-plane, half-helicopter on Wednesday in a quest for speed as competition heats up to define the rotorcraft of the future. The $217 million Racer is a one-off demonstrator model combining traditional overhead rotors with two forward-facing propellors in a bid to combine stability and speed, shortening response times for critical missions like search-and-rescue. "There are missions where the quickest possible access to the zone is vital. We often talk about the 'golden hour'," Airbus Helicopters CEO Bruno Even told Reuters, referring to the window considered most critical for providing medical attention. Such designs could also be offered for military developments as NATO conducts a major study into next-generation helicraft, though much depends on how its planners define future needs. [...] Racer's public debut came months after Italy's Leonardo and U.S. manufacturer Bell agreed to co-operate on the next generation of tilt-rotor technology, which replaces a helicopter's trademark overhead blades altogether. Leonardo is also leading a separate project to develop the next generation of tilt-rotors for civil use. Its AW609 is the sole existing civil design, but has yet to be certified. Proponents of the tilt-rotor, which relies on swiveling side-mounted rotors 90 degrees to go up and then forwards, say it permits higher speed and range that are suited to military missions. Critics say the tilt mechanism reaches higher speeds only at the expense of higher complexity and maintenance costs. Airbus said the Racer will fly at 220 knots (400 km/hour) compared with traditional helicopter speeds closer to 140 knots. Bell says its V-280 Valor tilt-rotor design, recently picked by the Pentagon, will reach a cruise speed of 280 knots. Watch: Racer - Inside the high speed demonstrator (YouTube)
