It's simply diverted away from the engine and out through exhaust pipes. There's no practical use for exhaust air once it passes through the power turbines. Read this article to learn how that thrust is created. Now that the propeller shaft is spinning at a reasonable speed, the propeller is able to generate thrust. About 70% of total engine power is dedicated to spinning the compressor section and engine driven accessories in a PT6. It's a self-sustaining cycle of power as long as the flame in the combustion chamber is lit. This is the same shaft that the compressor section and all engine driven accessories are connected to. As the hot, high-speed air flows over the turbine blades, they extract energy from the air, spinning the compressor 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 compressor turbine. Once the igniters light the fire, it is self-sustaining, and the igniters are turned off (although it's often used as a back-up in bad weather and icing conditions). The igniters are the last parts of the combustion stage they're 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. From there, the liner is where the actual combustion happens. And the fuel injector nozzles, as you probably guessed, spray fuel into the air, creating a fuel/air mixture that can be ignited. 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. In addition to that, air reverses direction again when it reaches the combustor, allowing for a shorter, more compact engine. Upon reaching the aft limit of the intake, the air makes a 180 degree turn back towards the front of the aircraft. Large air intakes underneath or beside the propeller scoop air into the intakes, where it moves backwards towards the engine firewall. Unlike turbofan or turbojet aircraft, air moves through turboprops like the PT6 by reverse flow. Because of its widespread popularity, it's a great example to focus on. While not all turboprop engines work exactly like the PT6, they all follow the same basic concepts. The 69 PT6 models range in power from 500 shaft-horsepower (SHP) to over 2,000 SHP. More than 41,000 PT6A engines have been produced since the family entered service in the 1960s, accumulating over 335 million flying hours. Of all turboprop engines, one of the most popular is the Pratt & Whitney PT6. Found on anything from a 50+ seat passenger aircraft to a single pilot cropduster, turboprop engines are perfect for safe, efficient regional travel.
