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 steering damper or steering stabiliser is a damping device designed to inhibit an undesirable, uncontrolled movement or oscillation of a vehicle steering mechanism, a phenomenon known in motorcycling as the death wobble. The stabilizer absorbs unwanted energy in the side to side motion allowing the forks and shocks to work properly.
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.
The turbine blades have a golden colour in this engine cutaway. A turbine blade is a radial aerofoil mounted in the rim of a turbine disc and which produces a tangential force which rotates a turbine rotor. [2] Each turbine disc has many blades. [3] As such they are used in gas turbine engines and steam turbines.
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 ...
[56] [108] To fully deploy the thrust reverser during landings, the yaw damper is connected to the steering of the nosewheel to provide greater stability. [109] In August 1974, the first RB199 powered flight of a prototype Tornado occurred and the engine completed its qualification tests in late 1978. [110]
Most of the loss, however, is caused by the curved and angled turbine blades, which do not absorb kinetic energy from the fluid mass as well as radially straight blades. Since the turbine blade geometry is a crucial factor in the converter's ability to multiply torque, trade-offs between torque multiplication and coupling efficiency are inevitable.
With a beam axle, the camber angle between the wheels is the same regardless of its location in the travel of the suspension. A beam axle's location in the fore and aft directions is constrained by one of several suspension components, including trailing arms , semi-trailing arms, radius rods, and leaf springs .
