The fastest helicopter in the world is the Eurocopter X3. The X3 can fly at speeds of up to 302 miles per hour.Know More
Unveiled in 2010, the Eurocopter X3 is a high-speed compound helicopter made by Airbus Helicopters. It was built using a propeller on each of its short span wings. Each propeller has a different pitch which helps it counter the torque effect of its main rotor. The design helps it to reach unheard of speeds for a helicopter.
The X3 first took to the skies in September, 2010 and its speed was first clocked in 2011. At that time, it flew at speeds of up to 267 miles per hour using only 80 percent of its available power.
Over the next 2 years, the X3 performed several other test flights around the world, and in June, 2013 it beat the unofficial record achieved by the Sikorsky X2 in 2010. During that flight, the X3 hit sustained speeds of 293 miles per hour and the speed of 302 occurred when the helicopter went into a shallow dive. For these speeds, the X3 is now considered the world's fastest non-jet augmented helicopter.
The X3 holds two crew members, weighs 11,464 pounds, and has a five-bladed main rotor along with a main rotor area of 1,342 square feet.Learn more about Airplanes & Helicopters
Attempts to create helicopters can be traced back to Leonardo da Vinci, but the first working prototype helicopter, the VS-300, was invented by Igor Sikorsky in 1939. The next model he designed was the R-4 in 1942, which was the world's first mass produced helicopter. Sikorsky pioneered the rotor configuration that is used on most modern helicopters.Full Answer >
In 2013, a test of the X3 helicopter set a record for helicopter speed at 255 knots, or about 293 miles per hour, according to Wired magazine. However, the average non-military helicopter cruises at a speed of about 130 to 145 miles per hour, claims Air Business International.Full Answer >
The average speed for a four-seat helicopter is 130 to 145 miles per hour. Because smaller helicopters have smaller engines, the average speed for a two-seat is 90 to 105 mph. The fastest helicopter on Earth as of 2014, the X3 Eurocopter, can fly at 300 mph.Full Answer >
The most-advanced helicopters can fly up to 300 miles before having to refuel. How long any particular helicopter can fly without refueling depends on the size, weight and age of the helicopter.Full Answer >
