Who invented helicopters?

Answer 1

Leonardo da vinci "invented" the concept. It is demonstrated in his drawings. But it wasn't until Sikorsky and others that the helicopter came into being as a flight worthy craft.
Many people worked on various kinds of helicopters over the years, so no one person invented the helicopter.

The single most important advance in helicopter design was by Juan Cierva of Spain when he developed an articulated rotor system on his auto gyro (gyroplane).

Next would be Prof. Focke of Germany, who built what was was arguably the first fully controllable helicopter (Fw-61) several years before Sikorsky.

Igor Sikorsky then built a helicopter in the US that reached full-scale production in 1942 (131 aircraft built). His design of one main rotor and a small tail rotor became the standard.

Earlier designs included:

• 400 BC, Chinese children playing with bamboo flying toys.
• 1480 Leonardo da Vinci designed an "aerial screw" flying machine.
• 1861 Gustave d'Amecourt demonstrated a small steam powered helicopter made of aluminum. It didn't get off the ground, but it was the first use of the word "helicopter".
• 1877 Enrico Forlanini in a park in Milan flew an unmanned steam driven helicopter 13 meters in the air. It stayed aloft for 20 seconds.
• 1878 in France Emmanuel Dieuaide flew a model more than 12 meters (40 feet) high for 20 seconds. It had two opposite spinning rotors and was powered through a hose from a boiler on the ground.
• 1885 Thomas Edison in the US built a helicopter but it failed to take off, exploding and burning one of his workers.
• 1901 Ján Bahýľ, a Slovak, used an internal combustion engine (petrol) to fly a model helicopter that flew 0.5 meters (1.6 feet) above the ground. In 1905 his helicopter flew 1.5 km at a height of 4 meters (13 feet).
• 1907, two French brothers, Jacques and Louis Brequet developed the Gyroplane No.1. The plane lifted its pilot up into the air about two feet (0.6 m) for a minute but it needed two people on the ground to keep it balanced.
• 1907 French inventor Paul Cornu designed and built a Cornu helicopter that lifted its inventor to 1 foot (0.3 m) and remained aloft for 20 seconds. This machine was later abandoned.
• 1908, Thomas Edison patented his own design for a gasoline powered helicopter with box kites attached to a mast, but it never flew.
• 1912 William J. Purvis and Charles A. Wilson applied for and received a patent for a "Flying Machine" of the helicopter type on June 4, 1912. With Purvis at the controls it flew 20 feet into the air.
• 1924, in Argentine Raúl Pateras Pescara's helicopter No. 3 could fly for up ten minutes. He also developed the idea of tilting the engine and blades to make the machine fly forward.
• Abert Gillis von Baumhauer received the first patent for a true working helicopter in 1927.
• 1937 The German Fw 61 broke all the helicopter world records and several of the aircraft flew during World War 2.
• In the US LePage had the patent rights for the German Fw 61, and he built the XR-1.
• Igor Sikorsky was competing with LePage to build the first military helicopter. Sigorsky developed a single small rotor on the tail to keep his VS-300 steady. His later model, the R-4, got military orders for over 400 before the end of the World War 2.
• At the same time Arthur Young was working for Bell Aircraft to eventually develop the Bell 47, the most popular civilian model for the next 30 years.

i thinnk Leonardo da vinci like drew one? a long time ago but he didnt make it
Leonardo Da Vinci invented the first most closed helicopter ideal model. But it wasn't stable at all. Later, it was improved by many other inventors

Igor Sikorsky, 1942. There were some similar aircraft previous to 1942, but Sikorsky'sdesign is considered universally to be "the helicopter". See the related link.

Long Bear

Russian born, US aeronautical engineer, Igor Sikorsky (1889-1972), designed and flew the first four engined aircraft in 1913 and designed the first successful helicopter in 1939.

As to why, I can only guess that he saw a need and fulfilled it, or somebody asked him, or he picked up on one of Leonardo Da Vinci's ideas.
There was a toy, c.2000 years old, which makes use of the same principle as da Vinci, discovered in China.

Leonardo da Vinci conceptualised a helicopter he didn't exactly invent on.

In 1784, French inventor, Launoy and Bienvenue created a toy with a rotary-wing that could lift and fly and proved the principle of helicopter flight.

The very first piloted helicopter was invented by Paul Cornu in 1907, however, this design was not successful. French inventor, Etienne Oehmichen built and flew a helicopter one kilometer in 1924. Another early helicopter that flew for a decent distance was the German Focke-Wulf Fw 61, invented by an unknown inventor.

Igor Sikorsky is considered to be the "father" of helicopters not because he invented the first successful helicopter, upon which further designs were based.
Helicopter was discovered by Leonado Davinci.

Date and How discovered-

In 400AD there was a helicopter style spinning toy. 1906 was the first manned flight in a helicopter.
