When was the Helicopter First Invented?

The helicopter is a rotorcraft that uses rotating blades to generate lift and propel itself through the air. While the concept of a rotating-wing aircraft dates back to the early 18th century, the modern helicopter as we know it today was first invented in the early 20th century. In this article, we will explore the history of the helicopter and answer the question: When was the helicopter first invented?

Early Concepts and Experiments

The idea of a flying machine with rotating wings was first proposed by Sir George Cayley, an English engineer and aviation pioneer, in the early 19th century. Cayley designed a glider with rotating wings, which he believed would be able to generate lift and stay aloft. However, his design was never built or tested.

In the late 19th century, Octave Chanute, a French-American engineer, began experimenting with gliders with rotating wings. Chanute’s designs were more advanced than Cayley’s, and he was able to build several gliders with rotating wings. However, his experiments were not successful, and he eventually abandoned the idea.

The First Helicopter-Like Machine

The first helicopter-like machine was built by Idreos in 1907. Idreos, a French engineer, designed a machine with a rotor that was powered by a gasoline engine. The rotor was made up of a series of flat blades that were connected to a central shaft. When the engine was turned on, the rotor began to rotate, generating lift and propelling the machine forward.

The First Controlled Flight

The first controlled flight of a helicopter-like machine was achieved by Paul Cornu, a French inventor, in 1907. Cornu’s machine was powered by a steam engine and had a rotor made up of a series of curved blades. On November 13, 1907, Cornu successfully flew his machine for a distance of 100 meters (330 feet) and reached a height of 2 meters (6.6 feet).

The First Practical Helicopter

The first practical helicopter was invented by Ferdinand von Zeppelin, a German engineer, in the 1920s. Zeppelin’s design was more advanced than previous attempts, and it featured a rotor made up of a series of lightweight, curved blades. The rotor was powered by a gasoline engine, and the machine was capable of carrying a small payload.

Modern Helicopters

The modern helicopter as we know it today was developed in the mid-20th century. The Westland Lynx, a British helicopter, was the first to feature a Fenestron tail rotor, which eliminated the need for a traditional tail rotor. The Bell 47, an American helicopter, was the first to feature a single main rotor and a tail rotor.

Key Milestones in Helicopter Development

• 1907: Paul Cornu achieves the first controlled flight of a helicopter-like machine.
• 1918: Eugene Eiffel, a French engineer, designs a helicopter with a rotor made up of a series of curved blades.
• 1920s: Ferdinand von Zeppelin develops the first practical helicopter.
• 1940s: Westland Lynx features a Fenestron tail rotor.
• 1940s: Bell 47 features a single main rotor and a tail rotor.

Conclusion

The helicopter has a long and fascinating history, dating back to the early 19th century. While early attempts at building a helicopter were not successful, the invention of the modern helicopter in the early 20th century marked a major breakthrough in aviation technology. Today, helicopters are used for a variety of purposes, including transportation, medical evacuation, and military operations.

Bullets List: Key Features of Modern Helicopters

• Main Rotor: A rotor that generates lift and propels the helicopter forward
• Tail Rotor: A rotor that counteracts the torque created by the main rotor
• Engine: A gasoline or diesel engine that powers the rotor
• Control Systems: A system that controls the pitch and yaw of the rotor
• Landing Gear: A system that allows the helicopter to take off and land safely
