How It Works – Helicopter Blades And It’s Rotary Wing Terminology!

Helicopters make an air move over airfoils to generate lift, but instead of having their airfoils in a single fixed wing like airplanes, they have them built into their rotor blades, which spin around at high speed. The rotors are like thin wings, “running” on the spot, generating a massive downdraft of air that blows the helicopter upward.

For most helicopters, the engine turns a shaft that connects to an input quill on the transmission; the main rotor mast comes straight out of the top of the transmission and the tailrotor driveshaft connects to an output quill 90 degrees out from the mast.
