HYDRAULIC POWER LEVEL 2 (2)
SYSTEM OVERVIEW
On the green system the normal source of pressure is the Engine Driven Pump (EDP) and as auxiliary source the Power Transfer Unit (PTU).
On the blue system the normal source of pressure is the electrical pump (E-Pump) and as auxiliary source the Ram Air Turbine (RAT).
NOTE: The blue electric pump can be used as an auxiliary power source for maintenance purposes on ground.
On the yellow system the normal source of pressure is the Engine Driven Pump (EDP) and as auxiliary sources the Power Transfer Unit (PTU) and the electric pump (E- Pump).
NOTE: The yellow system also has a hand pump dedicated to cargo door operation.
PTU
The Power Transfer Unit (PTU) is an auxiliary pressure supply for either the green or yellow systems without transfer of fluid between the two systems.
It operates automatically if there is a delta pressure of 500psi between the green / yellow or yellow / green hydraulic systems.
The side operating as a pump will take fluid from its associated reservoir and provide an output through the PTU manifold to the HP manifold.
The motor side is supplied from the HP manifold through the PTU manifold, and is connected to the return system.
Each section of the PTU has a case drain connection to the return system.
RAT
The Ram Air Turbine (RAT) is an auxiliary pressure supply for the blue system, and for the emergency electrical power CSM / G.It can be deployed automatically or manually depending on the failure
conditions.
The RAT is locked when extended.
An index lock mechanism will only permit RAT stowage if the blades are properly aligned.
It also prevents rotation when stowed. The index lock will release at approximately 5 degrees from the full extension position.
Extension is by spring force. Retraction (stowage) is by blue hydraulicpressure.
Up lock release is by solenoid operation.Down lock release is by hydraulic pressure.
