![]() As the hot, high-speed air flows over the turbine blades, they extract energy from the air, spinning the turbine around in a circle, and turning the engine shaft that it's connected to. ![]() The turbine is a series of airfoil-shaped blades that are very similar to the blades in the compressor. Once the air makes its way through the combustor, it flows through the turbine. Once the igniter lights the fire, it is self-sustaining, and the igniter is turned off (although it's often used as a back-up in bad weather and icing conditions). The last main part is the igniter, which is very similar to the spark plugs in your car or piston-engine airplane. The liner has several inlets, allowing air to enter at multiple points in the combustion zone. And the fuel injector, as you probably guessed, sprays fuel into the air, creating a fuel/air mixture that can be ignited.įrom there, the liner is where the actual combustion happens. The dome and swirler add turbulence to the air so it can more easily mix with fuel. ![]() The diffuser slows down the air from the compressor, making it easier to ignite. The case contains all the parts of the combustor, and inside it, the diffuser is the first part that does work.
