The center section of a sectioned Rolls-Royce Turboméca Adour turbofan displayed at the Musée de l’Air in Paris, France. Air flow is from right to left.
<p>The four-stage compressor (blue blades) compresses air from the core flow before delivering it to the combustors.

Bypass air is guided around the core. A tube carrying air bled from the compressor can be seen inside the bypass air duct; this bled air is used for the cooling of the second-stage turbine guide vanes.
