When was the First Helicopter?

The concept of a rotor-based aircraft dates back to the early 19th century, but the first practical helicopter was not built until the early 20th century. In this article, we will explore the history of helicopter development and answer the question: When was the first helicopter?

Early Concepts and Experiments

The idea of a rotor-based aircraft was first proposed by French inventor Clément Ader in 1890. Ader’s design consisted of a wooden frame with a rotating wing, which he claimed could lift off the ground and fly. However, his experiment was unsuccessful, and the concept was largely forgotten.

In the early 20th century, other inventors and engineers began to experiment with rotor-based designs. One notable example is the work of American inventor Paul Cornu, who built a small, single-rotor helicopter in 1907. Cornu’s design was powered by a gasoline engine and had a maximum altitude of 1 meter (3.3 feet). Although his experiment was not successful, it marked an important milestone in the development of helicopter technology.

The First Practical Helicopter

The first practical helicopter was built by French engineer Igor Sikorsky in the 1930s. Sikorsky’s design, known as the VS-300, was a single-rotor helicopter with a coaxial rotor system. The VS-300 was powered by a 75 horsepower engine and had a maximum altitude of 1,000 meters (3,300 feet).

Key Features of the VS-300

• Coaxial Rotor System: The VS-300 had two rotors that spun in opposite directions, which provided greater stability and control.
• Single-Engine Power: The helicopter was powered by a single engine, which reduced weight and increased efficiency.
• Autopilot System: The VS-300 had an autopilot system that allowed the pilot to control the helicopter’s altitude and direction.

First Flight of the VS-300

The VS-300 made its first flight on September 14, 1939, at Stratford, Connecticut. The flight lasted for 1 minute and 45 seconds, and reached an altitude of 10 meters (33 feet). Over the next few years, Sikorsky continued to refine his design, and the VS-300 became the first practical helicopter to be certified for commercial use.

Legacy of the VS-300

The VS-300 marked a significant milestone in the development of helicopter technology. Sikorsky’s design set the standard for modern helicopters, and his innovations paved the way for the development of more advanced helicopter designs.

Conclusion

The first helicopter was built by Igor Sikorsky in the 1930s. The VS-300 was a single-rotor helicopter with a coaxial rotor system, single-engine power, and an autopilot system. The VS-300 made its first flight in 1939 and became the first practical helicopter to be certified for commercial use. Today, helicopters are used for a wide range of applications, including search and rescue, medical transport, and military operations. The VS-300’s legacy continues to inspire innovation and advancement in the field of aviation.
