Fastest helicopter in the world



 The Sikorsky X2 now holds the record for the fastest helicopter in the World. During its recent test flight, this marvel of the air went to a peak of 416 km/h.

   It has two rotors instead of one, is operated by just one pilot and is quieter, with the ability to make sharper turns than a typical helicopter. Because the helicopter is powered by both its twin rotors and its pusher propeller, it has enough force to fly at 10,000 feet. Sikorsky X2 plan will be tested again to achieve speeds of 462 km/h. The previous record for the fastest helicopter was held by a Westland Lynx since 1986. In 1986 a Westland Lynx model ZB500, that was slightly modified, reached a speed of  249 mph or 401km/h, making it the world's fastest helicopter. But those world records may not stay unbroken for long.


The Eurocopter’s X3 hybrid helicopter can cruise at 264 mph, considerably faster than a conventional helicopter, and demonstrates unique maneuverability. The X3 airframe is equipped with two turboshaft engines that power a five-blade main rotor system and two propellers which are installed on short-span fixed wings. The American Helicopter Society  has presented its Howard Hughes Award for Outstanding Improvement in Helicopter Technology to Eurocopter’s X3 development team. Eurocopter advanced the hybrid configuration from concept to first flight in less than three years.


Boeing AH-64 Apache helicopter
Designed in the 1986, AH-64 Apache is arguably the most well known attack helicopter in existence. AH-64 is a four-blade, twin-engine attack helicopter with a tailwheel-type landing gear arrangement, and a tandem cockpit for a two-man crew.
