Main Rotor
The main rotor is a rotating component of a helicopter that generates lift and allows the helicopter to take off and land vertically, hover, and fly in any direction. It consists of a mast, hub, and rotor blades. The mast is a cylindrical metal shaft that extends upwards from the helicopter's transmission and supports the hub. The hub is attached to the top of the mast and holds the rotor blades. The rotor blades are long, narrow airfoils that are attached to the hub and rotate around the mast. The main rotor is powered by the helicopter's engine and is controlled by the pilot through the cyclic and collective controls. The main rotor is critical to the safe and efficient operation of a helicopter.
