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.
In an aircraft, a surface the function of which is to exert a turning moment about an axis of the craft.
A control surface on the trailing edge of the vertical part of the tail that is used to make the aircraft yaw. The rudder is controlled by rudder pedals. Pushing the left rudder pedal will tilt the rudder to the left. This will cause the nose of the aircraft to turn to the left.
A paddle or oar used for steering a ship/boat.
an upright blade that can be turned to left or right about a vertical axis, generally mounted on the transom and extending below the waterline to provide the means of turning a boat while underway.
vertical flap on the tail fin that directs left/right movement
A device under the shell of a boat used to steer it.
A movable, vertical surface that pivots back and forth to control yaw
A metal or wood plate on the stern of the boat used to direct the course of the boat.
The part of the airplane that controls the yaw (side to side motion) of the airplane.
the moving section on the back half of the fin. Used to control the airplanes yaw.
Part of the boat that sticks below the water and is used to steer the shell.
a swiveling panel in an aircraft's vertical tailfin turning the rudder swings the tail left or right
movable fin at the aft end of a boat used for steering.
The device for steering a boat.
The device that causes the boat to turn.
The vertical blade in the rear of the kayak, used to steer the boat.
A control surface, usually installed on the trailing edge of the vertical stabilizer, which controls the yaw motion of the aircraft - that is, the motion of the nose of the aircraft left and right.
A little fin on the bottom of the boat that the coxswain can control to steer the boat. RUN - The distance the boat moves after a stroke. Long run is very good. Run can be visually measured by the distance between the last puddle made by two-seat and where eight-seat's blade enters the water.
A vertical, metal or wooden plate attached under the hull or at the stern, whose movements steer the boat; See tiller
1. to drag the paddle to create resistance, causing the stern of a canoe to turn in the direction of the rudder side when performed by the sternsman. 2. a board or plate of wood or metal hinged vertically at the stern of a sprint kayak as a means of steering.
Small (often hand-size) pivoting fin mounted under the keel that steers the boat. Boats with coxes have rudders; also, quads do and doubles may; these are steered from bow seat, and are connected so that bow steers by pivoting one foot.
A vertically oriented control surface used to control yaw on airplanes. Also found on boats where it is used as the primary directional control device. Report this Word Added by: DCGayhart
Situated behind the fin, or on the stern of the boat, the rudder steers the boat when rotated about it's axis.
Yet another airplane term, but not as common as aileron and elevator. This is what controls the yaw of an airplane, and is synonymous with the tail rotor / vertical stabilizer aka "tail fin."
The machine by which the ship is steered.
Control surface located on the vertical tail that defects from side to side to change the sideforce on the aircraft and cause the nose to turn right or left.
Submerged part of the steering gear that determines the direction the boat will follow.
A squarish piece of material attached to the bottom of the boat just behind the fin.
To use the paddle to steer the canoe by turning its blade.
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
a control surface connected to the vertical stabilizer and used to yaw the aircraft
a device used to steer a ship or other watercraft
a flat-bladed steering apparatus controlled by a pair of foot pedals
a flat board that hangs from the back of the boat, attached to the tiller (handle) that is used to turn it
a generally flat or foil-shaped piece or structure attached vertically to the stern of a boat
a vertical panel on the back edge of the tail fin that swings from side to side to help maintain lateral control of an aircraft
a large flap on the vertical stabilizer (tail fin) that controls yaw.
Device on stern for steering a ship.
Movable control surface effecting control in yaw.
The blade-like implement that controls the boats course by being turnd from side to side underwater by the wheel or tiller.
A small fin that allows the coxswain to steer the boat.
Usually fitted to the back of a marathon or sprint boat and controlled by a foot pedal or foot operated steering bar.
any hinged controlled surface that allows left or right turns in the air
A board-shaped piece attached to the rudderpost or stern for steering and maneuvering
A device attached upright to the stern of a ship and used to steer it.
A hinged or pivoted vertical blade or flat that is turned to steer a boat.
A vertical blade in the stern of touring or sea kayaks that is usually turned side to side by the kayaker's feet to steer the boat.
used to steer the boat through the water, the rudder is connected to and controlled by the helm, but is in the water at the back of the boat
The rudder is a pivoting blade that steers the boat by the force of the water flowing over the flat vertical surface, capable of inducing drag on one side of the hull or the other.
A steering device under the shell of a boat at the stern. The rudder is connected to some cables (tiller ropes) that the coxswain can use to steer the shell.
A fin-like device astern and below the waterline which when turned to port or starboard will cause the bow of the ship to respond with a similar turn.
The equipment at the stern of the ship for controlling direction. Port rudder makes the ship turn anticlockwise if it is going ahead, clockwise if it going astern.
flat surface used to steer an airplane
the moveable control surface attached to the trailing edge of the fin that causes change about the yaw axis
mechanism on a ship used for steering it which was located in the rear of the ship. The rudder of a ship is frequently found on Roman coins and was a symbol of their military power. When seen with the goddess Fortuna it is the means by which she steers the world.
Steering device at the stern. The rudder in turn is connected to some cables (tiller ropes) that the coxswain can use to steer the shell. Older shells have short wooden handles (knockers) on the tiller ropes. These knockers are used by the coxswain not only to steer the shell, but also to rap out the cadence of the stroke rate on the gunwale.
a device that is used to steer a ship; a common type has a vertical fin at the stern and able to move from 35 degrees port to 35 degrees starboard; rudders are characterised by their area, aspect ratio, and shape the leading edge is at the fore edge when the ship is going ahead and at the aft edge when the ship is going astern a rudder may be balanced, semi-balanced, unbalanced or spade type
Typically a foot-controlled steering device on touring or sea kayaks.
Also formerly spelled 'rother'. The means of giving direction to a ship under way. Around the mid-14th century changed from an oar rudder, hung from the side of a ship, to a fixed stern rudder. The latter being a flat paddle, hung and hinging from the sternpost. See gudgeon and pintle. This pivoting lateral movement was transmitted to the rudder by a wheel, tiller and/or rope and pulley system, depending on the ship's size and time period.
The moving part of the vertical tail surface of an aeroplane which provides yaw control.
A vertical plate or board for steering a boat.
The vertical plane at the rear of a submarine or surface ship which is used to steer the vessel.
This is the term used to describe the part of the tail that moves back and forth. This movement causes the tail of a plane to move which then turns the plane. There are lots of planes that have only rudder and elevator for turning right and left and moving upwards and downwards. Then there are others that do fine with just ailerons and elevator. Then there are planes that have everything. These are known as Full House sailplanes. (The German word for rudder is Ruder. Click the Altavista Translator for more help translating instructions.)
The moving part at the back of the fin which controls the airplanes yaw.
The underwater, movable plate used for steering, and for providing resistance to sideways motion caused by waves and wind. It is being controlled by the helmsman (helmsperson?) with a help of a tiller or a steering wheel.
