What does a RAT do on a plane?
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.
How does the Ram Air Turbine work?
An aircraft’s Ram Air Turbine is a small auxiliary propellor that it can deploy in the event of a power loss. It works by generating power from the airstream passing over it as the plane flies, causing the turbine to rotate. The greater the speed of the aircraft, the more power the RAT will generate.
What does ram air mean?
Ram air refers to the principle of using the airflow created by a moving object to increase ambient pressure. Often, the purpose of a ram air system is to increase an engine’s power. The term “ram air” may also refer to: Parafoils, also called ram air parachutes, non-rigid airfoils inflated by wind.
What is the rat on a Airbus a319?
ram air turbine
A ram air turbine (RAT) is a small wind turbine that is connected to a hydraulic pump, or electrical generator, installed in an aircraft and used as a power source. The RAT generates power from the airstream by ram pressure due to the speed of the aircraft.
How is a rat deployed in an air turbine?
In normal conditions the RAT is retracted into the fuselage (or wing), and is deployed manually or automatically following complete loss of power. In the time between power loss and RAT deployment, batteries are used. RATs are common in military aircraft which must be capable of surviving sudden and complete loss of power.
Why are rats used in free fall nuclear weapons?
This allows their installation on a standard hardpoint, without requiring a pod-specific power supply. Also, some free-fall nuclear weapons, such as the British Yellow Sun and Red Beard, used RATs to power radar altimeters and firing circuits; these were a more reliable alternative to batteries.
What happens if you get a rat on your computer?
Generally speaking, a RAT won’t slow down your computer, and hackers won’t always give themselves away by deleting your files or rolling your cursor around the screen. In some cases, users are infected by a RAT for years without noticing anything wrong. But why are RATs so secretive? And how are they useful to hackers?
What kind of aircraft is powered by rats?
RATs are common in military aircraft which must be capable of surviving sudden and complete loss of power. In other military uses, pod-fitted systems such as the M61A1 Vulcan cannon or high-powered electronics such as the AN/ALQ-99 jamming system can be powered by a RAT in standard operation.
