How a turbine engine starts

Starting of a gas turbine engine requires rotation of the compressor to a speed that provides sufficient pressurised air to the combustion chambers. The starting system has to overcome inertia of the compressor and friction loads, the system remains in operation after combustion starts and is disengaged once the engine has reached self-idling speed. Web18 de dez. de 2024 · In other words, they straighten and stabilize the flow of air. Boldmethod. After passing the final axial flow compressor stage, the air moves to a centrifugal flow compressor stage. Air is thrown outwards, away from the engine core, and towards the combustion chambers. The air has made another 90 degree turn.
