a hinged vertical airfoil mounted at the tail of an aircraft and used to make horizontal course changes
(nautical) steering mechanism consisting of a hinged vertical plate mounted at the stern of a vessel
An underwater vane used to steer a vessel. The rudder is controlled by means of a wheel, tiller or other apparatus (modern vessels can be controlled even with a joystick or an autopilot).
A control surface on the vertical stabilizer of a fixed-wing aircraft or an autogyro. On some craft, the entire vertical stabilizer comprises the rudder. The rudder is controlled by foot-operated control pedals.
Origin: roþor, from rōþran, from rōanan "to row" from ere- + -þran, instrumental suffix. Akin to rowan. More at rōwan, -þor.
a riddle or sieve
the mechanical appliance by means of which a vessel is guided or steered when in motion. It is a broad and flat blade made of wood or iron, with a long shank, and is fastened in an upright position, usually by one edge, to the sternpost of the vessel in such a way that it can be turned from side to side in the water by means of a tiller, wheel, or other attachment

Origin: [OE. rother, AS. rer a paddle; akin to D. roer rudder, oar, G. ruder, OHG. roadar, Sw. roder, ror, Dan. roer, ror. 8. See Row to propel with an oar, and cf. Rother. ]
A rudder is a device used to steer a ship, boat, submarine, hovercraft, aircraft, or other conveyance that moves through a medium. On an aircraft the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull or fuselage, thus imparting a turning or yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical linkages or hydraulics.
