  2. Flap rudder - Wikipedia

    en.wikipedia.org/wiki/Flap_rudder

    The flap rudder is designed to improve the effective lift generated by the rudder and hence improve the manoeuvrability of the craft. The rudder consists of two or more sections which move relative to each other as helm is applied and the angle of the main or driven section moves, thus the shape of the rudder changes dynamically as the angle of helm is changed.

  3. Trim tab - Wikipedia

    en.wikipedia.org/wiki/Trim_tab

    Typical trim tabs on aileron, rudder and elevator. Trim tabs are small surfaces connected to the trailing edge of a larger control surface on a boat or aircraft, used to control the trim of the controls, i.e. to counteract hydro- or aerodynamic forces and stabilise the boat or aircraft in a particular desired attitude without the need for the operator to constantly apply a control force.

  4. Vertical stabilizer - Wikipedia

    en.wikipedia.org/wiki/Vertical_stabilizer

    The vertical stabilizer is the fixed vertical surface of the empennage. A vertical stabilizer or tail fin [1] [2] is the static part of the vertical tail of an aircraft. [1] The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it.

  5. Skeg - Wikipedia

    en.wikipedia.org/wiki/Skeg

    In the kayak, the amount of exposure of the skeg to the water, and also its effect on the position of the boat's centre of lateral resistance (CLR), is freely adjustable by the crew. The adjustment varies the degree to which the wind affects the boat – that is, the amount of lateral movement the wind can cause by impacting the upper parts of ...

  6. Rudder - Wikipedia

    en.wikipedia.org/wiki/Rudder

    A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, airship, or other vehicle that moves through a fluid medium (usually air or water). On an airplane, the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn

  7. Rudder pedal - Wikipedia

    en.wikipedia.org/wiki/Rudder_pedal

    A rudder pedal is a foot-operated aircraft flight control interface for controlling the rudder of an aircraft. [1] [2] The usual set-up in modern aircraft is that each pilot has a pedal set consisting of a pair of pedals, with one pedal for each foot. Each right and left pedal works together so that one pedal pops out when the other is ...

  9. Self-steering gear - Wikipedia

    en.wikipedia.org/wiki/Self-steering_gear

    Direct drive, in which an actuator is attached to the steering quadrant, at the top of the rudder stock inside the boat. This is the least intrusive method of installation. Wheel mounting, in which a motor is mounted near the steering wheel, and can be engaged with it when in use. This typically involves either a belt drive or a toothed gear ...
