Aircraft Gas Turbine Engine Exhaust Section

The components of the exhaust section include the exhaust cone, tailpipe (if required), and the exhaust nozzle. The exhaust cone collects the exhaust gases discharged from the turbine section and gradually converts them into a solid flow of gases. In performing this, the velocity of the gases is decreased slightly and the pressure increased.

Aircraft Gas Turbine Engines Types and Construction

Gas Turbine Engines Types. Turbine engines are classified according to the type of compressors they use. There are three types of compressors—centrifugal flow, axial flow, and centrifugal-axial flow. Compression of inlet air is achieved in a centrifugal flow engine by accelerating air outward perpendicular to the longitudinal axis of the machine.

How Gas Turbine Combustion Works | GE Vernova

Gas turbines generate power using pressurized air. The air is heated in a "combustor" and then it expands through the turbine. In turn, the turbine spins a generator that creates electricity. Another key part—the air compressor—is also powered by the turbine as it rests on the same shaft, pushing air into the combustion chamber.

Fundamentals of Gas Turbine Engines

The major components of the GTE are the compressor for the process from 1 to 2, the combustor for the process from 2 to 3, and the turbine for the process from 3 to 4. The heat rejection process from 4 to 1, which completes the cycle, is carried out by exhausting the hot gas and allowing it to mix with the atmosphere.
