X3 makes aviation history reaching 255 knots during level flight (Press release from Eurocopter, 11 June 2013)

 

The X3 reached 255 knots (472 km/h) in level flight on June 7, 2013, surpassing the unofficial speed record for a helicopter. Eurocopter achieved this historic milestone with the X3 flying at an altitude of 10,000 feet (3,048 meters) during a 40-minute test flight over southern France near Istres. Several days before, the X3 reached a speed of 263 knots (487 km/h) during a descent. This latest success completes the growing list of achievements for the X3.

 

"The X3 exhibited outstanding stability and provided a low vibration level without any antivibrationn system," said test pilot Hervé Jammayrac. "It's no exaggeration to say that the X3 is clearly in its element at high speeds."

 

With these latest flight milestones, the X3 demonstrator has accumulated a combined total of more than 140 hours aloft since making its maiden takeoff in September 2010. After easily surpassing the initial target of 220 knots, the demonstrator's speed was steadily increased while confirming the hybrid configuration's excellent flight qualities, maneuverability, outstanding acceleration and deceleration. In reaching these latest 255- and 263-knot speed achievements, Eurocopter has further confirmed the concept's potential.

 

A wide range of potential applications is envisioned for the X3, including in long-distance search and rescue (SAR) operations, coast guard missions, border patrol flights, passenger transport and off-shore airlift, inter-city shuttle services, and a range of military missions such as special forces operations, troop transport, combat SAR and medical evacuation.

 

"Based on the X3 technologies, Eurocopter will continue setting the standards on future helicopters – offering our customers new levels of performance in terms of speed, range and mission capabilities at competitive costs," said CEO of Eurocopter, Guillaume Faury. "The outstanding X3 achievements result from the commitment and excellence of our teams. I want to recognize everyone involved in the demonstrator's development."
