A helicopter is a type of rotorcraft in which lift and thrust are supplied by rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward, and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft would not be able to take off or land. The capability to efficiently hover also allows helicopters to be used for various purposes, including observation, transportation of goods and people, and search and rescue.
BACKGROUND
Helicopters are manufactured in a variety of sizes with a wide range of capabilities. The smallest helicopters, known as micro-copters, can seat only one person and have a rotor diameter of just over a meter. The largest helicopters, such as the Mil Mi-26, can seat up to 120 people and have a rotor diameter of more than 32 meters.
The first successful powered helicopter was flown by French inventor Paul Cornu in November 1907. Cornu’s helicopter used two counter-rotating rotors, each with two blades. By contrast, the majority of helicopters today use a single main rotor with two or more blades.

INTRODUCTION
A helicopter is a type of rotorcraft in which lift and thrust are supplied by rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward, and laterally. These attributes allow helicopters to be used in a wide variety of applications, including search and rescue, law enforcement, firefighting, and medical evacuation. A helicopter consists of three main sections: the cockpit, the main rotor, and the tail rotor.
COCKPIT
The cockpit is the aircraft’s control center. It is where the pilot sits to fly the helicopter. The cockpit typically has a set of flight controls, instruments, and other devices for piloting the helicopter.
MAIN ROTOR
The main rotor is the large, horizontal rotor that provides lift for the helicopter. It consists of two or more blades that rotate around a central mast. The main rotor is powered by the engine, which turns a driveshaft that connected to the rotor blades.
TAIL ROTOR
The tail rotor is a smaller rotor located at the back of the helicopter. Its purpose is to counter the torque created by the main rotor, which would otherwise cause the helicopter to spin. The tail rotor is powered by the same engine that powers the main rotor.
The main rotor and tail rotor are the two most important rotors on a helicopter. Together, they provide lift and thrust for the helicopter. The main rotor provides lift, while the tail rotor provides thrust. The cockpit, main rotor, and tail rotor are the three main sections of a helicopter. Each plays an important role in flying the helicopter.
How far can a helicopter travel
A helicopter can stay in the air for as long as it has fuel. The range of a helicopter depends on the type of helicopter. Some helicopters have a range of over 1,000 miles, while others have a range of only a few hundred miles. The difference between a helicopter and an airplane is that a helicopter can hover, while an airplane cannot. Helicopters are also able to take off and land vertically, while airplanes require a runway. Helicopters also have a tail rotor, which helps to counter the torque of the main rotor and keep the helicopter from spinning.
What is the difference between a helicopter and an airplane?
Ans: The main difference between a helicopter and an airplane is that a helicopter can hover, while an airplane cannot. Helicopters are also able to take off and land vertically, while airplanes require a runway. Helicopters also have a tail rotor, which helps to counter the torque of the main rotor and keeps the helicopter from spinning.
