Eurocopter is making a grand U.S. tour with its X3 hybrid developmental heloplane, which features a pair of conventional looking turboprops in addition to a conventional looking rotar.
The craft, which Eurocopter developed in just three years’ time, is nearly 100 knots faster than the fleetest comparably sized conventional helicopters. The X3 has achieved better than 230 knots in level flight, though it is not clear whether the craft qualifies as the world’s fastest helicopter, since it is technically more than a helicopter.
