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 afterend. Often rudders are shaped to minimize hydrodynamic or aerodynamic drag.
The rudder may also be called upon to counter-act the adverse yaw produced by the roll-control surfaces. If rudder is continuously applied in level flight the aircraft will yaw initially in the direction of the applied rudder – the primary effect of rudder. After a few seconds the aircraft will tend to bank in the direction of yaw.
A balanced rudder is a rudder in which the axis of rotation of the rudder is behind its front edge. This means that when the rudder is turned, the pressure of water caused by the ship's movement through the water acts upon the forward part to exert a force which increases the angle of deflection, so counteracting the pressure acting on the after part, which acts to reduce the angle of deflection.
INS Vikrant (pronounced [vikraːnt̪ə]) [22] is an aircraft carrier in service with the Indian Navy. The carrier is India's fourth carrier and the first to be built in India. It was constructed by the Cochin Shipyard Limited (CSL) in Kochi, Kerala. The name Vikrant is a tribute to India's first aircraft carrier INS Vikrant.
Paddle or rudder-type sponsons, which use a flat paddle-shaped rudder attached vertically to a block-type sponson, do essentially the same thing, but the effect can be even more dramatic, because the flat paddle or rudder portion of the sponson provides a sharper and more pronounced edge to catch the water.
The National Transportation Safety Board has more concerns about Boeing's planes. It said at least 40 airlines outside the US may be operating aircraft with risky rudder parts.
A fault with the rudder travel limiter was involved in the crash of Indonesia AirAsia Flight 8501. The design of the rudder travel limiter on the Airbus A300-600 was cited as a contributing factor to the crash of American Airlines Flight 587. In addition to a low rudder pedal sensitivity compared to other aircraft, the A300-600 had a variable ...
