The invention of the helicopter is a story that involves the contributions of several individuals over the course of centuries. While it is difficult to attribute the invention of the helicopter to a single person, the earliest recorded concept of a rotorcraft dates back to the 15th century. Leonardo da Vinci, the renowned Italian polymath, is often credited with designing the first helicopter-like machine, known as the "Aerial Screw," in 1485. Da Vinci's design consisted of a spiral rotor that was meant to lift a machine into the air, but it was never built during his lifetime.
Early Experimentation and Development
In the 18th and 19th centuries, several inventors and engineers experimented with rotorcraft designs, including Mikhail Lomonosov, a Russian scientist who built a rotorcraft model in 1754, and Sir George Cayley, an English engineer who designed a helicopter-like machine in 1796. However, these early designs were not practical for flight and were often limited by the technology available at the time.
Paul Cornu and the First Successful Flight
On November 13, 1907, Paul Cornu, a French inventor, achieved the first successful flight of a rotorcraft, which he called the “Gyroplane.” Cornu’s design used two rotors that rotated in opposite directions to cancel out the torque created by the spinning blades. The flight lasted for 20 seconds and covered a distance of 6 meters (20 feet) at a height of 1.8 meters (6 feet) above the ground.

Igor Sikorsky and the Modern Helicopter
In the early 20th century, Igor Sikorsky, a Russian-born American engineer, designed and built the first practical helicopter, the VS-300, in 1939. Sikorsky’s design used a single main rotor and a tail rotor to counteract the torque created by the main rotor. The VS-300 was the first helicopter to be capable of controlled, sustained flight, and it paved the way for the development of modern helicopters.
Technological Advancements and Modern Applications
Today, helicopters are used in a variety of applications, including search and rescue, medical transport, law enforcement, and military operations. The development of advanced materials and technologies, such as composite materials, computer-aided design, and advanced avionics, has enabled the creation of more efficient, reliable, and versatile helicopters. The helicopter has come a long way since its inception, and its evolution is a testament to human ingenuity and innovation.
The story of the helicopter's invention is a complex and fascinating one, involving the contributions of many individuals over several centuries. From Leonardo da Vinci's early designs to the modern helicopters of today, the helicopter has undergone significant transformations, driven by advances in technology and the imagination of pioneers like Paul Cornu and Igor Sikorsky.
