MARIGNANE, France, May 20 (UPI) -- A new helicopter has attained a speed of 267 mph in France, making it the fastest helicopter in the world, aviation experts say.
The X3 by French company Eurocopter achieves its high rate of speed by using an additional engine, separate from the one driving its main rotor, to power two conventional aircraft-type propellers, one on each side of the craft, PhysOrg.com reported Friday.
It can travel nearly twice as fast as conventional helicopters, which normally can achieve about 150 mph.
The system does not require any extra stabilizing or ballast systems to keep the configuration of one large rotor and two smaller propellers working together, nor does it require any autopilot or assistance systems and it can be flown by a normally qualified helicopter pilot.
The Eurocopter X3 is primarily aimed at emergency services and the military personnel for the extra speed if offers.
Eurocopter has not said whether it would make the X3 available to private buyers who have the means to make such a purchase.
