flapping hinge — A hinge connecting a rotor blade to the hub and about which the blade rises and falls (i.e., flaps during its rotation, and thus permits equalization of lift or rotor thrust) between the advancing blade half and the retreating blade half of the… … Aviation dictionary
flapping — The angular movement of a rotor blade above or below the plane of the hub. Blades ride higher and lower during their rotation, but they can do so only if they are allowed to move freely about a horizontal hinge or flexible root element. Design… … Aviation dictionary
flapping plane — The plane in which flapping occurs (i.e., a plane normal to the plane of the rotor disc) … Aviation dictionary
Helicopter rotor — This article is about helicopter main rotor systems. For antitorque control, see tail rotor. Helicopter rotor The rotor head of a Sikorsky S 92 A helicopter main rotor or rotor system is a type of fan that is used to generate both the aerodynamic … Wikipedia
teetering rotor — An arrangement in which a pair of rotor blades are joined at the hub, which is free to move in a flapping sense, with the flapping hinge line lying on the rotor axis. Also called a seesaw rotor … Aviation dictionary
blade flapping — The vertical movement of a helicopter rotor blade about a horizontal or flapping hinge, in which the blades tend to rise and descend with respect to the rotor hub as they rotate. Blade flapping tends to minimize asymmetrical lift by increasing… … Aviation dictionary
Fenstron antitorque rotor — A shrouded rotor to protect the tail and personnel around the helicopter from foreign object damage. A Fenstron tail rotor has no flapping ability but does have feathering capability. See also foreign object damage. Fenestron anti torque rotor … Aviation dictionary
fully articulated rotor — A rotor with three or more blades in which the individual blades are free to flap (move up and down), drag (move back and forth in the plane of rotation), and change their pitch angle as they rotate around the disc. This is done by mounting the… … Aviation dictionary
articulated rotor — A rotor in which the individual blades are free to flap (i.e., move up and down), drag (i.e., move back and forth in the plane of rotation), and change their pitch angle independently. This is done by mounting the blades on flapping and drag… … Aviation dictionary
door-hinge rotor — Articulated blades on flapping hinges visually resembling a door hinge … Aviation dictionary
Dissymmetry of lift — in rotorcraft aerodynamics refers to an uneven amount of lift on opposite sides of the rotor disc. It is a phenomenon that affects single rotor helicopters in lateral flight, whether the direction of flight be forwards, sideways or in reverse.… … Wikipedia
