Who Invented The Helicopter?

Leonardo da Vinci is made the first detailed drawings.  But he didn't really understand the physics of how it would work.  Long before da Vinci, the Chinese had come up with a child's toy that could hover briefly (using the energy from winding something up or an elastic band).

Inventors in following centuries kept tinkering with the idea, but they didn't have a strong enough engine to create the necessary power (and they didn't really understand how lift would work, either).

The internal combustion engine changed all that.  Suddenly the had enough power... but they also had a lot of unforeeseen problems.  Chief among these was torque, the tendency of the blades to push the helicopter fusealoge around in circles.  In 1907 a French engineer, Paul Comu, managed to lift a twin-rotor model off the ground for a few seconds, but this was slow progress.  In 1924 another Frenchman, Etienne Oehmichen demonstrated a helicopter that flew for over 7 minutes on a 1km course.  It still wasn't until the late 1930s that helicopters became reliable machines of flight.

Sikorsky invented the helicopter, but leo came up with the concept

Igor Sikorsky is the first who invented the helicopter in 1940. But Leonardo da Vinci was the first who had an idea of a helicopter.!

Except that he did not, Juan de La Cierva invented the first working helicopter

Igor did in 1940

Igor sikorsky made the first helicopter

Leonardo da vinci was the person who first represented an early helicopter idea in 15th century. The 1st real helicopter was invented by Russian man named igor sikorsky in the year 1940. He was a person who planned the first four-engine aero plane and the first successful helicopter.
