rotor system types — There are three types of rotors: rigid, semirigid, and fully articulated. In a rigid rotor, the blades are free to change pitch but otherwise are made as rigid as possible. The blades of rigid rotor have no hinges that allow them to flap or drag … Aviation dictionary
teetering hinge — A hinge connecting a rotor blade to the hub and about which the blade rises and falls (i.e., flaps during its rotation). This permits the equalization of lift (or rotor thrust) between the advancing blade half and the retreating blade half of the … Aviation dictionary

seesaw rotor — A rotor system in which the blades are fixed to the hub, generally by a teetering or seesaw hinge, allowing the blades to flap and feather but not lead lag or drag. The rotor pivots on the mast in much the same way a seesaw pivots on its fulcrum … Aviation dictionary
