The construction of each stage required the use of high-pressure, state-of-the-art hydraulic systems.
More radically still, pneumatic and hydraulic systems have been ditched for electric systems.
They use motors or hydraulic systems, and have batteries that need constant recharging.
Hydraulic systems tend to be designed similarly to pneumatic systems, except that hydraulic systems use hydraulic (liquid) pressure rather than air pressure.
In hydraulic systems, a pump driven by the engine maintains the fluid under pressure.
Electric power steering replaces the hydraulic systems of the previous models.
In fact, skilled Hawe employees are able to mill crucial parts of its hydraulic systems to tolerances of one micron.
Before, pilots maintained control by manipulating cables and hydraulic systems linking the cockpit to the wings and the tail.
Modern aircraft, for example, use hydraulic systems to activate their controls and to operate landing gears and brakes.
Fluid-power valves control pneumatic or hydraulic systems.
Inside, pilots train in a cockpit replica, while elaborate technological and hydraulic systems reproduce the reality of flight.
