12 Fastest Helicopters In The World That Only A Few Know About

Helicopters have been conceptualized more than 500 years ago. There is a sketch made by 1486 Leonardo da Vinci, in 1486, depicting a helicopter. However it took centuries to build a real working helicopter. In 1939 Igor Sikorsky designed and flew the first helicopter, called the VS-300. This helicopter was this first to incorporate a single main rotor and tail rotor design, like the modern helicopters. Helicopters were used initially for military purposes, for reconnaissance, and carrying wounded soldiers. Since then, helicopters have been used as gunships and for attacks. Helicopters have the advantage of not requiring a runway, which made them very versatile and useful.

There have been continuous attempts to make faster helicopters with powerful engines. The helicopter engines are rated, not on BHP or brake horse power; but on SHP or Shaft horse Power. The ideal engines must have a good weight-to-power ratio. The race for better efficient engines and faster helicopters was required for military and defence advantage. The defence forces and army are the biggest users of helicopters. Helicopter manufacturers developed faster and versatile multi-use helicopters for military use. This is the reason that that most of the fastest helicopter in the world are military helicopters. There are certain civil and commercial use helicopters which have high speed and many are civilian versions of the military helicopters.

Eurocopter is a subsidiary of Airbus Industries, which owns the patent of the futuristic helicopter. It has not yet been made operational, as it is still in its developmental and trial stage.

Helicopter will always remain the mainstay of army in the day to come. The technology and warfare is changing. Just as cavalry has given way to tank regiments; the helicopter also is proving to be a reliable and powerful warhorse. Its ability and versatility at low altitudes as well as 5.000 meters height of mountain tops makes it a real mean machine. The developments will also help civil aviation. Helicopters are now routinely and extensively used to ferry passengers at high altitude. They have also proved invaluable in saving lives of people and are increasingly being used as air ambulance. During natural calamities like floods, earthquakes etc. helicopters become the flying angels for humanity.
