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.
L'invention concerne un compresseur multiétagé (1) pour une turbine à gaz présentant un carter de compresseur (2), des aubes directrices (7), des aubes mobiles (6), une zone de moyeu (3), des orifices de purge (5) et des orifices d'insufflation (4) pour stabiliser le compresseur. Ce compresseur est caractérisé en ce que les orifices de purge (5) sont placés au moins un étage en aval des orifices d'insufflation (4). Ainsi, les problèmes de l'état de la technique sont résolus ; des rendements peuvent être sensiblement améliorés et le poids du mécanisme d'entraînement peut être réduit.
