Definitions

  • the flow-injection opening (4) may be located between a distance A from a trailing edge (112) of the guide vane (7); where distance A has a value of about 5% of a chord length (99) of the guide vane (7); and a distance C from a leading edge (118) of the guide vane (7); where distance C has a value in the range of 65% to 85% of a chord length (99) of the guide vane (7).
  • control valves 82 are shown. Each of these have an inlet 84 from a compressed air source for supplying compressed air to the vanes. Each of these control valves 82 are in fluid communication with a different fluid manifold 86, 88, each of the fluid manifolds 86, 88 being fluidly isolated from one another. Each vane 7 is in fluid communication with one of the different fluid manifolds 86, 88, but none are in fluid communication with both of the fluid manifolds 86, 88. Hence, in the example shown, the system enables flow injection to selected vanes 7. By controlling the control valves 82, all, some or none of the vanes 7 may inject flow into the compressor axial flow, as required.
  • a means of controlling rotor blade dynamic response at predetermined engine operating conditions thus extending rotor blade life by avoiding rotor blade resonant frequencies, or at least the duration for which such frequencies are generated.
  • the method and system of the present disclosure also increase the range of conditions at which an engine comprising the compressor system of the present disclosure may operate, thus optimising performance of the engine.
