Abstract: A compact gas turbine engine having improved fuel efficiency, lower emissions, better starting capability, and longer operational life is provided at low cost through the use of a combustor (40) incorporating tangential fuel injection (62) in conjunction with certain strategically placed and sized oxidant inlet jets (80, 82). The oxidant inlet jets include deflector jets (82) which deflect a generally circumferentially spiralling flow of gasses within the combustor in a manner causing fuel and oxidant to recirculate for a longer period of time within a primary combustion zone (86), to thereby improve combustion efficiency and reduce undesirable emissions. Apparatus and methods for regulating injection of the fuel and oxidant in or primary (98), secondary (100), and dilution zones (102) of the combustor (40) in a manner providing improvements in fuel efficiency, high altitude starting and other advantages are also defined.

Abstract: The cooling and mounting of vanes (50) in a turbine nozzle between shrouds (28, 29) is facilitated by impaling the vanes (50) with threaded fasteners (54, 70) and conducting relatively cool air from the compressor through the grooves (72) between adjacent threads (70) of the threaded fastener (54).
