Leonardo da Vinci (1452â1519) is generally credited with inventing the helicopter, but the first practical design was developed only in the 1930s by Russian-born Igor Sikorsky (1889â1972). Today, typical uses for helicopters include military transportation and air-sea rescue.eonardo da Vinci (1452â1519) is generally credited with inventing the helicopter, but the first practical design was developed only in the 1930s by Russian-born Igor Sikorsky (1889â1972).

In 1877, for example, Enrico Forlanini flew a large steam-powered model to a height of over 40 feet in Milan. But it wasn't until 1907 that the Frenchman Paul Cornu hovered just off the ground for 20 seconds in a strange 32-bladed helicopter. Cornu, like the Wright brothers four years earlier, was a bicycle-maker. Several other early helicopters were made, but they were all underpowered and hard to control.
