description In 1938, United Aircraft – which had bought Sikorsky’s company – granted him permission to create an experimental helicopter design. Eschewing the coaxial rotors that had been used up to that point, Sikorsky used a single three-bladed main rotor and a two-bladed vertical rotor on the tail to offset torque.

What inspired the creation of the helicopter?

During the mid-1500s, Italian inventor and artist Leonardo Da Vinci (1452–1519) made drawings of an ornithopter flying machine, a fantastical machine that might have flapped its wings like a bird and that some experts say inspired the modern helicopter. The toy proved the principle of helicopter flight.
