11rigid rotor — A rotor head that allows the blades freedom to feather but not to flap or lead lag. The rotor head has to absorb all the forces generated during flight maneuvers. Control loads in this type of rotor head are high; however, this type imparts the… …
12tail rotor drift — A side force produced by the tail rotor which, unless corrected, causes the helicopter to move sideways on the ground. The main rotor thrust is offset to produce a side thrust to correct for the tail rotor drift. This tendency must be corrected… …
13seesaw 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 …
14articulated 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… …
15Center of gravity of an aircraft — The center of gravity (CG) is the point at which an aircraft would balance if it were possible to suspend it at that point. It is the mass center of the aircraft, or the theoretical point at which the entire weight of the aircraft is assumed to… …
16Autogyro — 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… …

18helicopter — /hel i kop teuhr, hee li /, n. 1. any of a class of heavier than air craft that are lifted and sustained in the air horizontally by rotating wings or blades turning on vertical axes through power supplied by an engine. v.i. 2. to fly in a… …
19Swashplate (helicopter) — This article is about the swashplate in helicopters, see also the swashplate article which describes all uses of the mechanism. A swashplate is a device that translates the pilot s (or autopilot s) commands via the helicopter flight controls into …
