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).

Today, let's look for the first helicopter. The University of Houston's College of Engineering presents this series about the machines that make our civilization run, and the people whose ingenuity created them. It's frustrating to try to find the first helicopter. Leonardo da Vinci had the idea of pulling himself into the air with a vertically mounted propeller, and the idea was seductively simple. But for the next four and a half centuries one inventor after another ran into terrible problems when he actually tried to do it.
