What is the principle of flying helicopter?

Wings create lift because of a relationship called the Bernoulli Principle. A helicopter’s rotor blades are wings and create lift. An airplane must fly fast to move enough air over its wings to provide lift. A helicopter moves air over its rotor by spinning its blades.

How does a helicopter autorotation work?

Definition. Autorotation is a state of flight in which the main rotor system of a helicopter or similar aircraft turns by the action of air moving up through the rotor, as with an autogyro, rather than engine power driving the rotor. It is analogous to gliding flight in a fixed-wing aircraft.

What control does the pilot flying a helicopter use to compensate for main rotor torque?

The tail rotor is used to control the heading of the helicopter while hovering or when making hovering turns, as well as counteracting the torque of the main rotor. Hovering turns are commonly referred to as “pedal turns.”

How does a Chinook helicopter work?

Lift, in a Chinook helicopter, is produced by a rotor system consisting of two fully articulated counter-rotating rotors. The forward rotor is driven by the forward transmission through the rotor drive train. The aft rotor is driven by the aft transmission through a vertical drive shaft.

What are the 4 flight controls for helicopter?

A helicopter has four controls: collective pitch control, throttle control, antitorque control, and cyclic pitch control. The collective pitch control is usually found at the pilot’s left hand; it is a lever that moves up and down to change the pitch angle of the main rotor blades.

Where is the Chinook?

Chinook, North American Indians of the Northwest Coast who spoke Chinookan languages and traditionally lived in what are now Washington and Oregon, from the mouth of the Columbia River to The Dalles. The Chinook were famous as traders, with connections stretching as far as the Great Plains.
