The Eurocopter X3 (X-Cube) is an experimental compound helicopter under development by Eurocopter. It is intended to fly at speeds of over 220 knots (250 mph; 410 km/h). The X3 demonstrator is based on a Eurocopter EC155 helicopter with the addition of short span wings each fitted with a tractor propeller. The tractor propellers are gear driven from the two main turboprop engines which also drive the five-bladed main rotor. The helicopter is designed to prove the concept of a high-speed helicopter which depends on the slowing down of the rotor speed to avoid drag from the advancing blade tip, and to avoid retreating blade stall by unloading the rotor while a small wing takes up lift instead. The X3 first flew on 6 September 2010 from French Délégation Générale de l'Armement facility at Istres-Le Tubé Air Base. On 12 May 2011 the X3 flew at a speed of 430 km/h (267 mph) for several minutes. General characteristics: Crew: 2 Length: ft in (m) Rotor diameter: ft in (m) Height: ft in (m) Disc area: ft² (m²) Empty weight: lb (kg) Powerplant: 2 × Rolls-Royce Turbomeca RTM322 turboshaft, 2,270 shp (1,693 kW) each Main Rotor: five-bladed, with two five bladed tractor propellers gear driven off main engines. Performance: Cruise speed: 220< knots (407 km/h) Service ceiling: 12500 ft (3810 m) Rate of climb: ft/min (m/s).
