Humans have all the time looked at birds with envy and wished that they could fly up in the sky with them. Throughout the history of man there have been a lot of attempts at defying gravity.
The very first effort to originate a 'machine' that was capable of flying was easily a form of helicopter. This was invented in China, and it was easily a uncomplicated toy rather than whatever that could carry a man. The child would twirl the toy around in their palms until sufficient lift is created and it can be released.

The first realistic helicopter originate was created by Leonardo Da Vinci in the 15th century. Unfortunately Leonardo's visions were never made into full size models due to the technology of the day not living up to the requirements. The designs created by Leonardo were way ahead of their time.
There were many other attempts at creating something that resembled a helicopter over the next centuries. However until the end of the 19th century the technology just wasn't good sufficient to make the dream a reality. Until then there just wasn't whatever good sufficient to furnish sufficient power in order to originate sufficient lift.
Of course things easily started to take off with the coming of the internal combustion engine. The internal combustion machine allowed the helicopter a viable possibility. However even with this technology many dissimilar problems were encountered. This was caused by a lack of understanding of all the corporal principles, mainly torque and balance. The very first prototypes had a tendency to flip themselves over. Others were very difficult to control, that is if they ever easily managed to get up into the air.
In 1907 a French originator created a helicopter that used a twin-rotor system. This managed to lift off the ground for a mere concentrate of seconds. There wasn't much further revising until 1924 when an additional one French man managed to make a controllable flight which lasted over 7 minutes.
Over the next concentrate of years there were dozens of more thriving attempts by the French, British, Dutch, Russian and Spanish to name but a few. In 1936 However the helicopter started to look like the contemporary day helicopter. The German Focke-Wolfe Fw 61 was capable of flying up to 143 miles at 11,240 feet.
This started helicopter flight in earnest. Later companies like Sikorsky, Bell, and Mil would originate helicopters that would come to be the basis for the contemporary day helicopter.
