This assembly may in turn form part of another servomechanism. A potentiometer provides a simple analog signal to indicate position, while an encoder provides position and usually speed feedback, which by the use of a PID controller allow more precise control of position and thus faster achievement of a stable position (for a given motor power).
Hydrosteer was the name given by George Kent Ltd and Cam Gears Limited through Hydrosteer Limited [1] of Luton, England, to its automotive power steering system. Initially Hydrosteer manufactured the Ross-Link system for commercial vehicles from 1953 under licence from Ross Gear and Tool of U.S.A. [2] Their own product available from 1961 was based on a cam and peg system and was characterised ...
Jury-rigging can be applied to any part of a ship; be it its super-structure (hull, decks), propulsion systems (mast, sails, rigging, engine, transmission, propeller), or controls (helm, rudder, centreboard, daggerboards, rigging). Similarly, a jury mast is a replacement mast after a dismasting. [2]
A cyclist steering a bicycle by turning the handlebar and leaning. Steering is the control of the direction of motion [1] or the components that enable its control. [2] Steering is achieved through various arrangements, among them ailerons for airplanes, rudders for boats, cylic tilting of rotors for helicopters, [3] and many more.
The Braine steering gear was a fine-tuned system of quadrant on the rudder stock driven by the tension of the mainsail sheet and damped by a rubber band. A more sophisticated system called the vane gear was later devised, it relied on a small vane or airfoil driving the main rudder via an adjustable system
The rudder attaches to the skeg and is steered by cables attached to it. In select sweeping boats, typically fours and eights, a coxswain will control the rudder, while in sculling boats and some sweeping boats, especially pairs, the rudder will be controlled with toe-steering. [4] A skeg typically consists of a flat piece of metal or plastic. [5]
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.
English inventor Francis Ronalds described what he called a propelling rudder in 1859 that combined the propulsion and steering mechanisms of a boat in a single apparatus. . The propeller was placed in a frame having an outer profile similar to a rudder and attached to a vertical shaft that allowed the device to rotate in plane while spin was transmitted to the propell
