What is Airbus RAT?
Description. A Ram Air Turbine (RAT) is a small turbine that is installed in an aircraft and used as an alternate or emergency hydraulic or electrical power source. The RAT generates power from the airstream based on the speed of the aircraft and is connected to an electrical generator or to a hydraulic pump.
Does the b737 have a rat?
No the Boeing 737 does not have a Ram Air Turbine (RAT) as it doesn’t need one. In the event of a dual engine failure the windmilling engines can deliver hydraulic pressure by their associated Engine Driven Pumps (EDP), and the EDPs are further backed up by Electrical Motor Driven Pumps (EMDP).
What does the rat do on an Airbus A320?
The Ram Air Turbine, or RAT, on the A320 is a backup electrical system. In the event of dual engine failure, or a serious electrical problem, the RAT will deploy. The RAT is a small propellor connected to a hydraulic pump and emergency electrical generator which will restore limit electrical power to the aircraft.
Where is the Rat Man on an A320?
The RAT MAN ON pushbutton (located on the “EMER ELRC PWR” section of the overhead panel on the A320) will deploy the RAT manually. Note however in this case, the emergency generator is connected to the aircraft’s electrical circuit 3 seconds after the RAT supplies the emergency generator.
How does a rat work in a hydraulic system?
The RAT can be deployed for emergency use to pressurize the blue hydraulic system. When the RAT MAN ON switch is selected on the hydraulic panel, the RAT, coupled to a hydraulic pump, extends and pressurizes the blue system. The RAT can be stowed only on the ground.
What is the role of the ram air turbine on an Airbus A320?
The role of the Ram Air Turbine on the Airbus A320 is to act as an electrical backup in the event of a serious emergency. The RAT can be deploy either automatically, or manually when selected by the pilots. The A320 RAT automatically deploys when the following conditions are met:
