  • Gas turbine engine
    Patent number: 8413418
    Abstract: A gas turbine engine (10) having a pressure-rise combustor (30) and the pressure-rise combustor (30) is positioned upstream of a stage of turbine nozzle guide vanes (32). The vanes (33) of the stage of turbine nozzle guide vanes (32) forms an ejector and each of the vanes (33) has an upstream portion (34) and a downstream portion (36). The upstream portions (34) of the vanes (33) have leading edges (38) and the upstream portions (34) are arranged substantially straight and parallel to define constant area mixing passages (40) for a flow of gases there-through. The downstream portions (36) of the vanes (33) are arranged at an angle to the upstream portions (34) of the vanes (33) to turn the flow of gases there-through.
    Type: Grant
    Filed: November 13, 2009
    Date of Patent: April 9, 2013
    Assignee: Rolls-Royce PLC
    Inventors: Samuel A. Mason, Mark D. Taylor, Torbjorn O. Lindquist, Robert J. Miller, Jonathan J. H. Heffer
  • Gas turbine engine
    Patent number: 8166747
    Abstract: A steam injection gas turbine engine having a once-through steam generator (OTSG). A condenser is provided downstream of the OTSG to capture water and is protected from hot flue gasses during startup by a bypass circuit. Optionally, heating the exhaust downstream of the condenser using coolant taken from an intercooler provides plume suppression.
