Helicopters are amazing machines that are capable of being used in countless applications. Their vertical take-off and landing capabilities make them invaluable to medical, military and private industry. With all the positives that these machines possess, there has always been one fundamental flaw – speed. For example, the U.S. Military’s Apache helicopter, a machine that is at the forefront of modern warfare, has a top speed of around 190 mph and is considered to be one of the most advanced machines in the world. Enter now the Sikorsky X2 coaxial-rotor helicopter, a machine with the capability to run speeds of up to 290 mph. The X2 looks like a cross between a Virgina Class submarine and a modern day helicopter, and pushes the limits of what was once thought achievable by a rotor driven aircraft. If you are looking for what’s in store for the future of rotor-driven flight well then, here is a glimpse of what is on the horizon.
