How does a jet engine handle rain?
As the incoming air moves into the rotating fan blades, the spinning motion flings the heavier water outward like a centrifuge. The water is then blown through the bypass air ducts that surround the engine core. In this way, the water is carried through the engine without ever entering the combustion chamber.
Can you flood a turbine engine?
They do. Turbine engines can tolerate a lot of water, and are tested as shown in the photo above. As you can see, massive amounts of water are injected into the intake, far more than in the worst rainstorms.
Why does a jet engine take so much air?
The first thing to understand is that jet engines take a lot of air. That’s why they can handle bizarrely heavy rainfall or even water on the runway splashing into the engine from the tires (this water jet has the fun name “rooster tails”).
How does rain and snow affect jet engines?
Effect of Rain & Snow on Jet Engines. Another design feature that helps keep a jet engine operating in heavy precipitation is igniters, similar to spark plugs, in the combustion section. In the event that the engine suffers a flameout, the igniters will re-ignite the fuel-air mix and restart the engine.
How is water carried through a jet engine?
The water is then blown through the bypass air ducts that surround the engine core. In this way, the water is carried through the engine without ever entering the combustion chamber. This design allows a turbofan engine to remove the majority of water that it will ever ingest while flying through a storm.
How are jet engines affected by standing water?
This practice is also recommended when taking off from a runway with standing water since the landing gear can throw up a sheet of water that may be ingested by the engines causing a flameout. Some modern engines are equipped with electronic systems that detect the state of the combustion process and tell the flight crew to engage the igniters.
