Thanks to his innovative thinking, today humans can fly without wings. Consider it a miracle of nature or a necessity of time. A human who once traveled for months on land and sea is now able to travel millions of miles in just a few hours thanks to his innovative thinking and invention.

Thus, most of us must have traveled by plane at least once in our lives, but a related vehicle that is rarely used for riding due to its flight and the nature of its work is called a helicopter. This man-made air machine is called a helicopter. Today, whether it is on the battlefield or in a rescue mission, this small but remarkable invention is considered more powerful and better than any aircraft. 

Despite all these features and advantages, this machine is quite similar to all other air machines due to the use of mechanical engines. Today, helicopters consist of different types of engines that provide power to perform tasks in different weather conditions. In the early years of the helicopter's development, it was equipped with the power of a piston engine. 

These engines worked exactly like the piston engines found in cars, in which the piston moves up and down inside the combustion cylinder, rotating the crankshaft, which is connected to the main rotor in front. These engines are usually installed in light and small helicopters, the main purpose of which is to provide low-level and training flights.

Within a short time, thanks to technological advances, these engines were replaced by turboshaft engines. This engine, in addition to being lighter in weight, works exactly like a jet engine with a few basic changes, creating pressure in the air and burning fuel, which provides power to rotate the turbine connected to the rotor. In addition to being light, these engines provide special help to helicopters in flying at high altitudes, in bad weather and on difficult routes. However, the fuel and maintenance costs of these engines are also quite high. These engines are usually used in combat, defense and rescue helicopters.

Today, due to environmental pollution, while other technologies such as cars and motorcycles, etc. are being made environmentally friendly, helicopters are also part of this environmentally friendly race of innovation, thanks to which today electric-powered helicopters have been developed, in which engines have been replaced by fast-rotating electric motors and batteries. But so far this project has not proven to be very effective. Therefore, these environmentally friendly helicopters are being used for short trips and low-level flights, but this advance in helicopter technology will prove useful in the near future.

When it comes to environmentally friendly helicopters, it is necessary to mention hybrid engines, which are playing an important and sustainable role along with electric helicopters today. These engines are equipped with the ability to generate electricity instead of being directly connected to the rotor of the helicopter, the main purpose of which is to provide power to the electric motor installed in the helicopter, enabling the helicopter to fly long and high.

If we look at it today, this man-made air machine is not only providing the passenger with a different flying experience, but is also playing a fundamental role on many important fronts where we cannot even imagine the use of other flying machines.

"If the helicopter did not exist today, could any other invention replace it?"
