World’s fastest helicopter revealed

The future of helicopters gets better. The Sikorsky X2, although a prototype, is currently the fastest helicopter which just broke the 258 MPH speed barrier. The key to the design is the unique co-axial tri-blade of the X2, which enables the helicopter to travel longer distance at a higher speed. But the objective of the X2 is even more ambitious. The target speed is actually 287.5 mph!

The other innovative technologies incorporated in this high-speed helicopter are:

• Fly-by-wire flight controls
• Counter-rotating rigid rotor blades
• Hub drag reduction
• Active vibration control
• Integrated auxiliary propulsion system

A Westfield LYNX ZBX-500 held the original speed record of 249 MPH since 1986, until now.
