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
Power steering is a system for reducing a driver's effort to turn a steering wheel of a motor vehicle, by using a power source to assist steering. [1]Hydraulic or electric actuators add controlled energy to the steering mechanism, so the driver can provide less effort to turn the steered wheels when driving at typical speeds, and considerably reduce the physical effort necessary to turn the ...
Each stage is a stationary ring of nozzle guide vanes followed by spinning blades. The gas is moving from left to right and the 2nd and 3rd vane rings have been removed to better show the blades. The first ring shows the shape of the vanes and how they turn the gas from the combustor into a tangential direction necessary to spin the bladed disc.
A rotor wake induces on the downstream stator blades a fluctuating vane loading, which is directly linked to the noise emission. Consider a B blades rotor (at a rotation speed of ) and a V blades stator, in a unique rotor–stator configuration.
Any rotor system has a delay between the point in rotation where the controls introduce a change in pitch and the point where the desired change in the rotor blade's flight occurs. This difference is caused by phase lag, often confused with gyroscopic precession. A rotor is an oscillatory system that obeys the laws that govern vibration—which ...

The steering mechanism can be designed and installed as a modular unit. Without mechanical connection between the steering wheel and the road wheel, it is less likely that the impact of a frontal crash will cause the steering wheel to impact the driver. Steering system characteristics can easily be adjusted to change the steering response and feel.
Differential steering is the primary means of steering tracked vehicles, such as tanks and bulldozers, is also used in certain wheeled vehicles commonly known as skid-steer, and even implemented in some automobiles, where it is called torque vectoring, to augment steering by changing wheel direction relative to the vehicle.
