Abstract (en)

[origin: WO2013107489A1] The invention relates to an air-assisted injection system for the compressor system of a turbo machine, wherein a recirculated or an externally fed primary mass flow requests a secondary mass flow from the outer region of the compressor housing utilizing the ejector effect, allows an effective stabilization of the compressor flow and counteracts a rotating flow separation on the compressor blades.
