Who Created the First Helicopter?
The invention of the helicopter is a remarkable story that involves the work of several pioneers and inventors over the course of several centuries. While there were many attempts to build a rotor-based aircraft, the first successful helicopter was created by Igor Sikorsky, a Russian-born engineer and inventor.
Early Attempts
The concept of a rotor-based aircraft dates back to the early 16th century, when Leonardo da Vinci sketched out designs for a machine that used rotating blades to generate lift. However, it wasn’t until the late 19th and early 20th centuries that the first serious attempts were made to build a practical helicopter.

**The Pioneers**
Several inventors and engineers made significant contributions to the development of the helicopter, including:
• Clément Ader: A French inventor who built the first powered, rotor-based aircraft in 1890. Ader’s machine was powered by a bicycle engine and had a small rotor that was designed to generate lift.
• Paul Cornu: A French engineer who built the first practical helicopter in 1907. Cornu’s machine was powered by a gasoline engine and had a rotor that was 7 meters (23 feet) in diameter.
• Henri Fabre: A French inventor who built the first successful autogyro in 1909. Fabre’s machine used a rotor to generate lift, but did not have a powered propeller.
**Igor Sikorsky: The Father of the Modern Helicopter**
Despite the progress made by these pioneers, the development of the helicopter was slow and often plagued by technical challenges. It wasn’t until the 1930s that Igor Sikorsky, a Russian-born engineer and inventor, made the breakthrough that would lead to the creation of the modern helicopter.
Sikorsky was born in Kiev, Ukraine in 1889 and began his career as an engineer in the Russian Navy. He immigrated to the United States in the 1920s and began working on his own aircraft designs.
Sikorsky’s Breakthrough
Sikorsky’s breakthrough came in the early 1930s, when he developed a new type of rotor design that used a single main rotor to generate lift. This design was more efficient and reliable than earlier attempts, and it paved the way for the development of the modern helicopter.
**The VS-300: The First Practical Helicopter**
In 1939, Sikorsky completed the VS-300, the first practical helicopter. The VS-300 had a single main rotor and a tail rotor, and it was powered by a 75 horsepower engine. The machine was 7 meters (23 feet) tall and had a rotor diameter of 10 meters (33 feet).
The VS-300 made its first flight on September 14, 1939, and it was a remarkable success. The machine flew for 10 minutes, reaching a height of 10 meters (33 feet) and a speed of 30 kilometers per hour (19 miles per hour).
**The Legacy of Igor Sikorsky**
Igor Sikorsky’s invention of the first practical helicopter has had a profound impact on modern aviation. Today, helicopters are used for a wide range of purposes, including search and rescue, medical transport, and military operations.
Sikorsky’s legacy extends beyond his own inventions, however. He founded the Sikorsky Aircraft Corporation, which became one of the leading helicopter manufacturers in the world. He also established the Igor I. Sikorsky Memorial Award, which is presented annually to outstanding engineers and inventors in the field of aeronautics.
Comparison of Early Helicopters
| Helicopter | Year | Rotor Diameter | Engine Power | Flight Time |
|---|---|---|---|---|
| Cornu’s Helicopter | 1907 | 7 meters (23 feet) | 10 horsepower | 10 seconds |
| Fabre’s Autogyro | 1909 | 5 meters (16 feet) | 20 horsepower | 5 minutes |
| Sikorsky’s VS-300 | 1939 | 10 meters (33 feet) | 75 horsepower | 10 minutes |
Conclusion
The creation of the first helicopter was a long and difficult process that involved the work of many pioneers and inventors. While there were many attempts to build a rotor-based aircraft, it wasn’t until Igor Sikorsky’s breakthrough in the 1930s that the modern helicopter was finally developed. Today, helicopters are an essential part of modern aviation, and they continue to play a vital role in a wide range of applications.
