Abstract (en)

[origin: WO2007051444A2] Disclosed is a multistage compressor (1) for a gas turbine, comprising a compressor housing (2), guide vanes (7), impeller vanes (6), a hub area (3), discharge ports (5), and injection ports (4) to stabilize the compressor. The inventive multistage compressor is characterized in that the discharge ports (5) are disposed at least one stage downstream of the injection ports (4), thus solving the problems of prior art while making it possible to significantly increase efficiency and reduce the engine weight.
