there is increase demand for electrical power in the aircraft. The trend in the aircraft industry is to replace hydraulic and pneumatic systems with electrical systems achieving more comfort and monitoring features. Moreover, the structure of MEA distribution system improves aircraft maintainability, reliability, flight safety and efficiency.

In the 1950s, a hydraulic leak occurred roughly once every 17.5 hours of flight time in military aircraft. In the 60s, the occurrence was reduced to once every 23.8 hours. The latest records, for 1980 through 1996, show a reduction in leakage frequency to once every 50 hr of flight.

Another method is the brushless system. In this system the armature of the exciter is on the rotor shaft itself. The DC output of this armature, after rectification by solid-state devices, goes to the rotor coils. Since the armature and rotor are on the same rotating shaft, this eliminates the need for slip rings.

May 10, 2000· 400Hz = (24000RPM * 2poles)/120 --aircraft 400 Hz (see how 12000 RPM and 4 poles, or 6000RPM and 8 poles can be interchanged) now look at EMF = 4*Φ*T*f since f is higher than say, current, T and Φ can be reduced in proportion to create the same amount of voltage.

The correct type of hydraulic fluid must use to assure proper system operation and to avoid damage to nonmetallic components of the hydraulic system. Principal categories of hydraulic fluids are minerals, polyalphaolefins and phosphate esters. When servicing a hydraulic system, use the correct category of replacement fluid. Mineral-based hydraulic fluid (MIL–H-5606) is processed from petroleum.

The Schottky diodes are implemented in Die 2 for efficient rectification at 120 MHz and a modified type II controller. For smooth power-up, a soft start circuit is implemented in Die 1. At power-up, the soft start circuit provides PWM signals with slowly increasing duty to slowly charge the output voltage to a preset level slightly lower than ...

An electro-hydraulic servo mechanism comprising: a hydraulic actuator formed with a pair of hydraulic chambers and having an output member which is displaced by a differential pressure between the hydraulic chambers, the output member being connected with an object to be controlled; an electro-hydraulic converter for varying the differential pressure between the hydraulic chambers in response ...

Rationale: Commercial aircraft maintenance personnel continue to have difficulties adequately addressing external hydraulic leakage on aircraft.

Hydraulic fluid reservoirs are required by most aircraft systems to provide a ready source of fluid for the hydraulic pump(s) and to contain a varying volume of fluid. This variance results from differential actuator volume (dependent upon whether the actuator is extended or retracted) and for fluid thermal contraction or expansion.
