When Was the Helicopter Invented? A Historical Timeline of the Pioneers Behind the Invention

Introduction

The helicopter is one of the most iconic pieces of machinery in human history. Its ability to take off and land vertically, hover in the air, and even fly backwards has made it a powerful tool for transportation, rescue, and warfare. But when was the helicopter invented?

A helicopter is defined as an aircraft that is propelled by one or more horizontal rotors. The rotor blades generate lift, allowing the aircraft to take off, hover, and move in any direction. This type of aircraft is also known as a rotary-wing aircraft or a chopper.

In this article, we will explore the history of the helicopter, from its earliest attempts at flight to its development into the powerful aircraft it is today. We will take a look at the pioneers who helped make the invention of the helicopter possible, and how their efforts have changed the course of history. Finally, we will discuss the technological advances that led to the invention of the helicopter and its impact on modern life.

A Historical Timeline of the Helicopter: When Was It Invented?

The concept of the helicopter has been around for centuries, with many inventors attempting to create a flying machine that could take off and land vertically. However, it wasn’t until the early 20th century that the first working helicopters were developed.

Early Attempts at Flight

The earliest known attempt to build a rotary-wing aircraft was made in 1483 by Italian artist, inventor, and scientist Leonardo da Vinci. Da Vinci designed a device called an “aerial screw” which consisted of a wooden frame with four linen-covered wings that were connected to a central shaft. He believed that this device could be used to lift a person off the ground and fly them through the air. Although da Vinci never built a working model of his design, his ideas laid the foundation for future inventors.

The First Working Helicopters

In 1907, French inventor Paul Cornu created the first successful rotary-wing aircraft. His prototype was powered by two 24 horsepower engines and had two counter-rotating rotors. Although the aircraft only hovered for about 20 seconds, it was enough to prove the concept of the helicopter.

In 1939, Russian-born inventor Igor Sikorsky created the world’s first practical helicopter, the VS-300. This aircraft was powered by a single engine and had three rotors. It was capable of vertical takeoff and landing, hovering, and forward flight.

Modern Day Developments

Since then, helicopter design and technology has advanced significantly. Modern day helicopters are powered by turbine engines, which allow them to reach speeds of up to 250 miles per hour. They are also equipped with sophisticated navigation systems, autopilot capabilities, and other high-tech features.

The Pioneers Behind the Invention of the Helicopter

Throughout history, there have been many innovators who contributed to the development of the helicopter. Let’s take a look at some of the most influential figures in the history of the helicopter.

Leonardo da Vinci and His Contributions to Flight

As previously mentioned, Leonardo da Vinci was one of the first people to develop a concept for a rotary-wing aircraft. His aerial screw design was the basis for the modern day helicopter. Although da Vinci never built a working model of his design, his ideas inspired many future inventors.

Igor Sikorsky and His Role in the Development of the Helicopter

Igor Sikorsky is widely regarded as the father of the modern helicopter. His VS-300 prototype was the first successful rotary-wing aircraft, and it paved the way for future designs. Sikorsky continued to refine his design, eventually creating the R-4, the world’s first mass-produced helicopter.

Other Innovators Who Contributed to the Evolution of the Helicopter

In addition to da Vinci and Sikorsky, there have been many other innovators who have contributed to the evolution of the helicopter. French aviator Louis Bréguet developed the first gyroplane, a forerunner to the modern day helicopter. German engineer Anton Flettner created the first fully-automated helicopter in 1932. And in 1943, Hungarian engineer György Jendrassik developed the first helicopter with an automatic stabilization system.

How Helicopters Changed the Course of History

The invention of the helicopter has had a profound effect on the course of history. Here are some of the ways that helicopters have changed the world.

Use in War

Helicopters have been used extensively in warfare since the 1950s. During the Korean War, helicopters were used to transport troops, supplies, and equipment. In Vietnam, they were used for search and rescue operations, medical evacuations, and reconnaissance missions. Today, helicopters are used in a variety of military operations, including air strikes, troop transport, and reconnaissance.
