Helicopters are delegated rotorcrafts. It utilizes rotors to supply the push and lift required for flight. The helicopter is one of a kind in that it can take off and land vertically. It is additionally fit for floating, flying forward, in reverse, and along the side. The possibility of vertical flight has existed since 400BC, when Chinese toys made of bamboo imitated the trip of cutting edge helicopters. During the 1480s Leonardo da Vinci structured a machine on paper that he accepted would be equipped for vertical flight. The principal operational helicopter, called the Focke-Wulf Fw 61, was worked in 1936. The primary helicopter to be put into full generation was a helicopter planned by Igor Sikorsky in 1942. Today helicopters are utilized for transportation, military, diversion, battling fires, and for salvage and medicinal crisis transportation.

In 1861 a machine was called a helicopter, but it could not lift off the ground.

Chinese invented a flying toy that had some of the same principles as the helicopter.

Helicopters are designed with spinning rotors, which can include two or more blades that provide the lift and thrust that make vertical flight possible.

Leonardo Da Vinci had sketches of a helicopter-like flying machine.

Most helicopters have two rotors, one on the top and one on the tail.

two French men (Launoy and Bienvenu) built a feathered-model helicopter.

Because helicopters are capable of vertical take-off and landing they are ideal for accessing difficult to reach locations in emergency situations.

Sir George Cayley invented the steam-driven chopper.

Helicopters tend to be much noisier than airplanes, and they vibrate a lot.

Paul Cornu built a full-sized helicopter. It cleared the ground for a few minutes, but remained tied down by ropes.

Helicopters are capable of hovering but it is a difficult maneuver to control due to the air flow created by the rotors of the helicopter itself.

Professor Theodore von Karman and Lieutenant Stefan Petroczy built a working helicopter. However, because it didn’t carry passengers, it was not officially recognized.

If the helicopter’s engine stops, the rotor will often allow the helicopter to land safely because it continues to spin.

Gerald P. Herrick converted an airplane into a helicopter. It was able to land at a steep angle.

It is believed that there are approximately 45,000 helicopters operating around the world today. This number includes military helicopters.

The German-made Focke Achgelis Fa 61 was the first official helicopter.

There is a nut holding the main rotor to the shaft of the helicopter, called the ‘Jesus nut’. This nut was named as such when a pilot said, “Oh Jesus, if that nut comes off…”

Igor Sikorsky made the first practical flight in the United States.

Helicopters can be used to lift heavy items into place. The Russian helicopter MIL Mi-12 Homer could lift 40,204kg to a height of 2255 meters.

It took 29 days, 3 hours, 8 minutes and 13 seconds for H. Ross Perot, Jr. and J.W. Coburn to circle the entire Earth in a helicopter. They broke the World’s Record.

The first person was rescued at sea by a helicopter in 1944. It is estimated that the use of helicopters has saved more than 3 million lives in war and peace times around the world since then.

NASA is studying the helicopter to see if it could be used on Mars.

Helicopters are also referred to as helos, whirlybirds, choppers, and copters.

the fastest helicopter can reach speeds up to 400 kilometers-per-hour (248 miles-per-hour).

In 2002 a helicopter crash in Chechnya resulted in the deaths of 114 passengers. There were 147 people on board, which exceeded the helicopter’s capacity by 1.5 times.

A helicopter is a type of airplane known as a vertical takeoff and landing craft (VTOL). It can have a long body or it can be short and compact. The helicopter does not have wings like an airplane. Instead it has long blades or rotors. These are attached to a shaft in the engine. It also has a tail on it with smaller rotors. The pilot uses a foot pedal and two specialized pitch sticks to control the helicopters direction.

Helicopters travel at speeds much slower than airplanes, but the advancing rotor blade can exceed the speed of sound.

If helicopters were not designed as well as they are, the vibration would be capable of shaking them apart.

The fastest recorded speed of a helicopter is roughly 248 miles per hour.

The farthest a helicopter has traveled without landing is 2213 miles.

Helicopters are often used to take photographs and film footage from the air.

Helicopters can help fight forest fires as they can carry helibuckets full of water to be dropped on strategic areas.
