The X3 flew at a speed of 255 knots in level flight, beating the previous record set in 2010 by the Sikorsky X2 compound helicopter, which was of 250-knot. Eurocopter also added that the X3 reached a speed of 263 knots in a  dive.

The results are still not confirmed, but once they are, the X3 will officialy become the fastest helicopter ever.

 “It’s no exaggeration to say that the X3 is clearly in its element at high speeds.” said Eurocopter test pilot Hervé Jammayrac. “While flying at both 255 knots and 263 knots, the X3 performed exactly as it has throughout its flight envelope, exhibiting outstanding stability and providing a low vibration level without any anti-vibration system.”

Rolls-Royce Turbomeca was proud to be associated with this speed record since the X3 helicopter has a RTM322 engine in it. The RTM322, is described by Rolls-Rpyce as “a state-of-the-art design & architecture engine family combines power and growth potential”.
