Helicopters

A rotorcraft or rotary wing aircraft is a heavier-than-air flying machine that uses lift generated by wings, called rotor blades, that revolve around a mast. Several rotor blades mounted on a single mast are referred to as a rotor.

A helicopter is a type of rotorcraft.

These aircraft can land in a small space, take off without running along the ground, and stay still, or hover, in the air. It depends for its support in flight on the lift generated by one or more rotors. Besides its main, or lift rotor, the helicopter usually has an auxiliary or tail rotor. This is a small rotor, mounted at the tail to counteract the torque of the main rotor. The tail rotor diverts some part of engine power and lowers the power plant efficiency. The coaxial rotor system is free from this drawback, but is not capable of high forward speed because of the drag of the widely separated rotors.

High cost of manufacture, heavy fuel consumption, restricted range and speed make the helicopter impractical for long range transportation. Even the best helicopter makes an endurance not exceeding 3 – 4 hours. The helicopter is at its best mostly on short trips – city centre to airport, for instance. Sling loading is often used because it is suitable for transportation of cumbersome loads and also because it does not require a labor force on the ground.
