Air (19, 119) captured from the tips (25, 125) of a compressor (10, 110) of a gas turbine engine is diverted from the engine core (22, 122) and can be collected for auxiliary uses. Gas path separation can be achieved using part-span shrouded compressor blades or using blade tip cut-outs (24) conforming to an airflow dividing annular shroud. The gas turbine may be, for example, an auxiliary power unit of an aircraft. The compressor includes a radial outflow impeller downstream of the rotor and a stator interposed between the impeller and the rotor. |
