ABSTRACT:
In an axial-flow compressor, the appliance for extracting secondary air using a peripheral extraction slot which is at least partially configured as a diagonal diffuser is such that means which make it possible to utilize the kinetic energy of the peripheral component of the flow velocity are arranged in or directly at the extraction slot (4). These can, for example, be a mini-cascade (7) integrated in the extraction slot (4) or an extraction slot (4) which is designed as a diagonal diffuser (8) and merges into a volute (9), the volute (9) opening directly into the extraction tube (6). The total pressure loss is minimized and the efficiency of the installation is increased by these arrangements.
