More than five hundred years ago, the Italian genius Leonardo da Vinci scribbled the human flying machine known as da Vinci’s helicopter. Unfortunately, da Vinci was unable to find the required light and durable material for the blades, and the technology of his time was unable to provide perpetuated power to his device. The dream of da Vinci was fulfilled by a Russian immigrant in the USA, Igor Sikorsky, who invented the world’s first practical helicopter. His invention VS-300 took flight at Stratford, Connecticut, on September 14, 1939. His design was the first to include a single main rotor and tail rotor. On May 04, 1943, Sikorsky received the patent for helicopter controls and won the title of the inventor of the helicopter.
