Components of jet engines

Common card · No. 427759

This article describes the components and systems found in jet engines. It uses two example engines; the type most familiar to the general public, the modern airliner engine, and the military afterburning engine. The components and systems make up what is known as a bare engine. The article also has a section on inlets. Although the inlet is not part of the engine, the engine relies on it to help prevent compressor surging (by reducing inlet distortion), and to give a pressure boost to the engine which reduces its fuel consumption (by converting the relative speed of the approaching air into pressure). The article also mentions the nacelle because the outside of an airliner engine has to be streamlined so that as little of its thrust as possible is lost to the drag of the air flowing past the engine.
