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
delta-three hinge — A hub hinge arrangement that is a coupling effect between either the flapping or lead lag hinge and a blade pitch. A blade has a delta three hinge if the movement of the blade in either axis causes the blade pitch to change. Pitch change rod… … 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
offset hinge — A helicopter main rotor hinge at a substantial distance from the axis of rotation. As compared with flapping hinges, offset flapping hinges provide better longitudinal and lateral stability and a wider center of gravity limits and permit the… … Aviation dictionary
elastomeric hinge — A rotor hinge made of elastomer (a rubberlike compound). It combines flapping, lagging, and pitching degrees of freedom in one unit and at one location. The elastomeric bearing consists of concentric laminations of elastomer and metal bonded… … Aviation dictionary
door-hinge rotor — Articulated blades on flapping hinges visually resembling a door hinge … 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
Autogyro — An autogyro is a type of rotorcraft invented by Juan de la Cierva in 1919, making its first successful flight on January 9, 1923 at Cuatro Vientos Airfield in Madrid. [http://www.vectorsite.net/avheli 1.html#m4 Vector Flight] ] Similar to… … Wikipedia
Juan de la Cierva — This name uses Spanish naming customs; the first or paternal family name is De la Cierva and the second or maternal family name is Codorníu. Juan de la Cierva … 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
