the steering of DS/ID/GS have no inherent feel (when once vehicle is moving that is, non-assisted ID and GS obviously very stiff at stand-still). the stiffness/heaviness at stand-still is not a question of feedback or kickback. Diravi adds a self-centering force (artificial feel) to a steering system which is otherwise devoid of feel, anyway.
Only the rudder pivots; the propeller itself is on a fixed shaft and does not. "Kitchener gear" or "Kitchener rudder" have been common misnomers for the Kitchen rudder. It is held under British Provisional Patent No. 3249/1914 and US Patent No. 1186210 (1916) and has been improved with the design in US Patent 4895093 (1990).
The steering engine is open to public view. A functional description is given in the 1965 book Str. Belle of Louisville, by Alan L. Bates, the marine architect who supervised the restoration of the boat, who comments that when in use, the steering engine causes the pilot wheel to whirl "as fast as an electric fan." The same source also ...
However, in this case two complete differentials are used, one for each track, and the idlers are controlled not by a brake, but a second power shaft, the steering shaft. [2] Normally the steering shaft is connected to the engine directly, instead of the output from the transmission. This means it spins at a relatively narrow range of RPM ...
The main goal of a mechanical self-steering gear is to keep a sailboat on a given course towards the apparent wind and to free the helmsman from the steering job. An advantageous side effect is that the sails are kept in optimal angle towards the apparent wind and deliver optimal propulsion force by that. Even in sailboats running under engine ...
The higher the angular momentum, the greater the resisting force of the gyro to external torque (in this case more ability to cancel boat roll). A gyroscope has three axes: a spin axis, an input axis, and an output axis. The spin axis is the axis about which the flywheel is spinning and is vertical for a boat gyro.
A cross-drive steering transmission is a transmission, used in tracked vehicles to allow precise and energy-efficient steering. It consists of the following main parts: two identical single-stage planetary gearings, a differential, a hydraulic pump connected to the engine (similar to an oil pump of cars), a hydraulic motor powered by the ...
The difference between a saildrive and a Z-drive is that a saildrive's propeller shaft is fixed in place, pointing aft, whereas a Z-drive's propeller shaft can be rotated to any azimuth. Traditional sailboat transmissions consist of a simple horizontal output shaft extended rearward from the engine, through the stern via a stuffing box. The ...
