Product catalog summary
Overview of Boeing 777 Hydraulic Systems
The Boeing 777 features three hydraulic systems (left, center, and right) operating at 3000 psig (207 bar) to control flight systems, flaps, actuators, landing gear, and brakes. The left and right systems are powered by engine-driven pumps (EDP) and electric motor-driven pumps (ACMP) from Eaton, while the center system uses air turbine-driven pumps (ADP) and primary electric motor pumps (ACMP). In emergencies, a ram air turbine (RAT) provides hydraulic power.

Eaton's Role in Boeing 777 Systems
Eaton supplies essential components such as electro-mechanical actuators, door mechanisms, and thrust reverse interlock actuators. The Quantitative Debris Monitoring (QDM) system detects ferrous debris in lube oil, providing early warnings for potential gear or bearing failures.

Hydraulic System Components
Each system uses Eaton's integrated hydraulic filter module. Eaton's brake metering valve controls brake pressure, and the main landing gear priority valve manages hydraulic power during peak demands. The emergency passenger door actuator uses nitrogen gas pressure for door operation.

Additional Eaton Products
Eaton provides components like main engine fuel pumps, pressure refueling level control valves, and landing gear swivels. The Boeing 777 incorporates advanced technology, including fly-by-wire controls and digital avionics, with a capacity of 305 to 440 passengers over 7,250 to 8,820 nautical miles.

Aerospace Capabilities Boeing 777-2

The Boeing 777 is a wide-body, twin-engine airplane with flexibility in range, routes and interior configurations. Its state-of-the-art technology includes fly-by-wire flight controls and digital avionics. Similar in appearance to the 767, the Boeing 777 is longer and wider with wings that include a folding wing-tip option. The landing gear on the 777 is the largest ever incorporated into a commercial airplane to date. The standard two-post arrangement features six-wheel trucks instead of conventional four-wheel units. A total of 12 wheels support the 777 for better weight distribution during...
