The word helicopter was first coined by Gustave de Ponton d’Amecourt in 1861 and stems from the Greek words helix (spiral or circle) and pteron (wing).

The helicopter is a machine that flies like a bird, but it has no wings. It lifts itself into the air by means of one or more sets of whirling wings called blades.

There are two kinds of helicopter: single-rotor and multi-rotor. The single-rotor type has one set of blades mounted horizontally on top of the fuselage, or body, in a position where it can be driven by an engine through suitable gearing. The multi-rotor type has several rotors, usually three or four, mounted vertically around the fuselage to provide both lift and forward thrust. A few helicopters have been built with five rotors, while some experimental models have nine rotors.

The great advantage of the helicopter over all other flying machines is its ability to rise straight

The rotor blades on the helicopter are what keeps them in the air. They rotate on top of the helicopter, and this creates an upward thrust that counteracts gravity, keeping the helicopter in the air. A helicopter can move vertically, horizontally and even backward because it doesn’t need a runway or forward speed to fly.

The idea of creating such a vehicle has been around for many years, but it took a lot of time to make it a reality. The first working model was created by Leonardo da Vinci back in 1481. It was called an “aerial screw” and was based on four frames with screws attached to them. It never saw flight, however. The real helicopter design was created much later – in 1907 by French inventor Paul Cornu, who managed to make his craft lift off 1 foot off the ground, only to crash moments later. The first stable flight happened in 1939 when Igor Sikorsky designed his VS-300 model which is considered to be the first practical helicopter design out

Helicopters are a type of aircraft which is equipped with a rotor that provides lift. The main difference between helicopters and other types of aircrafts are the blades. Helicopters are equipped with two main rotors (blades) in the horizontal axle. These rotors provide lift and propulsion for the helicopter to fly.

The blades on helicopters are often abbreviated as “rotor blades” or “rotor” for short. They create thrust by applying aerodynamics. Since helicopters require a large amount of power to operate, they are commonly powered by turboshaft engines or turbines. Turbine engines are designed to produce more power than piston engines as they require more power to operate efficiently. Turbine engines also have more power generated at lower altitudes which is ideal for helicopters since they hover at low altitudes. Most turbine engines used in helicopters today consist of two main parts, the power turbine and free turbine.

Turboshaft engines provide less torque than other types of engines but are better suited for helicopters due to their higher altitude capabilities and lower weight per horsepower ratio compared to other types of aircraft engines such as piston engines or gas turbines. Another reason why turboshaft engines are used more commonly

Helicopters are a type of aircraft which is equipped with a rotor that provides lift. The main difference between helicopters and other types of aircrafts are the blades. Helicopters are equipped with two main rotors (blades) in the horizontal axle.The rotors spin at high speeds and this allows the helicopter to fly even when it is not moving forward. It can hover in one place or move sideways, backwards and forwards without turning. This makes helicopters extremely useful in rescue situations and they can also be used as taxis in crowded cities.

Helicopters are a type of aircraft which is equipped with a rotor that provides lift. The main difference between helicopters and other types of aircrafts are the blades. Helicopters are equipped with two main rotors (blades) in the horizontal axle. Both blades rotate in the same direction, but at different speeds to prevent them from turning around their own axis, but instead around the vertical one. On top of that, there is often a small tail rotor that helps the helicopter stay balanced and straight during flight. This is all due to the fact that when you have a spinning object, such as rotor blades, it generates forces called ‘torque’, which would normally make the helicopter spin around its own axis. To counteract this torque effect, the tail rotor is used to provide the necessary force to keep it straight. The tail rotor itself is also a spinning device that generates more torque in the opposite direction, thus preventing the helicopter from spinning.

Every single part of a helicopter has its purpose and function in order for it to remain airborne and stable. A helicopter can be considered to be an aircraft that can fly both vertically and horizontally and also hover in mid-air without moving forward or backward. Helicopters are most commonly used as rescue or emergency

A helicopter is a type of aircraft which is equipped with a rotor that provides lift. The main difference between helicopters and other types of aircrafts are the blades. Helicopters are equipped with two main rotors (blades) in the horizontal axle.

The vertical rotor is used to control the direction of the vertical rotor in most helicopters, while the tail rotor is used to control the direction of the horizontal axis by providing thrust. These two rotors are connected to each other through a transmission system, which allows both main rotors to spin at different speeds.

The first helicopter was invented in 1907 by Henri Farman. The first helicopter that was able to fly freely and make a controlled flight with a pilot was invented by Igor Sikorsky in 1939. Early helicopters were built in Russia, France, Germany and the United States.

The main parts of a helicopter are the fuselage, rotor system, tail, landing gear and the control system. The function of the control system is to change the direction of the aircraft. The rotor system consists of the rotor head, blades and mast. The rotor head connects the blades to the mast which rotates above the cabin with a horizontal axle.

In this type of aircraft, lift is generated by rotating wings (blades) that work similar to an air screw or propeller. However, unlike propellers they rotate vertically and have much wider range of rotation. This ability allows helicopters to take off vertically without needing a long runway like other types of aircrafts do. Also they can hover in mid-air and fly backwards with ease.
