Abstract: The combustion dynamics and efficiency of a gas tubine having an annular combustor (26) provided with fuel injection nozzles (50) that inject fuel generally tangentially is improved by providing the walls (32, 34, 39) of the combustor (26) with cooling air film injectors (70, 86; 72, 88; 74, 90) at substantially equally angularly spaced locations about each such wall and which are oriented to generally tangentially inject a film-like air stream on the associated wall (32, 34, 39).

Abstract: Increased turbine inlet temperatures and/or extended life of turbine rotors in gas turbine engines is achieved by locating a plurality of passages (50) that extend axially in the disc (46) and turbine blades (32) of a so-called monorotor. The passages (50) have inlets (54) between compressor blades (18) on the rotor (20) and exit openings (52) in the free edges (38) of the turbine blades (32). Thus, air compressed by the compressor blades (18) is flowed through the passages (50) to cool the rotor (20).

Abstract: The expense of variable inlet guide vane structure for rotary compressors is avoided in a structure including a compressor housing (20) with an inlet (24) and a rotor (10) journaled within the housing (20) by disposing a housing (42) about the inlet end (24) and having an inlet port (54) over a minor fraction of its periphery. One or more guide vanes (60) may be disposed within the inlet port (54) to impart preswirl to incoming air as it enters the housing (42).

Abstract: Duplication of engine and secondary power system components in individual auxiliary and emergency power units is avoided in an integrated power unit including a gas turbine engine (10) having a centrifugal compressor (28) and a turbine (40), a generator (18) coupled to the engine (10), an air inlet (22) to the compressor (28), a first reservoir (82) for combustible fuel, and a first combustor (34), (36) for receiving and combusting compressed air from the compressor (28) and fuel from the reservoir (82) to generate gases of combustion and feeding the gases of combustion to the turbine (40) by the provision of a second reservoir (80) for containing a compressed oxidant for combusting fuel from the first reservoir (82), a second combustor (48) for receiving and combusting fuel from the first reservoir (82) and oxidant from the second reservoir (80) to generate gases of combustion, flow paths (64), (66), (68) for introducing fuel from the reservoir (82) into the gases of combustion from the second combustor (48) to vaporize the fuel and a conduit (50), (52) for directing the combined gases of combustion and vaporized fuel to the turbine (40) to drive the same. The apparatus is useful as an auxiliary power unit when the combustor (34), (36) is in use and an emergency power unit or starter when the combustor (48) is in use.

Abstract: A narrow efficient operating island for a centrifugal compressor may be increased in a construction including a compressor section (18) mounting blades (22) surrounded by an annular shroud (38) by placing bleed passages (88) in the shroud (38) and angling them in the direction of flow, both axially (Fig. 1) and radially (Fig. 3).

Abstract: A self starting turbine (10) is disclosed. An auxiliary pulse combustor (23) is provided having a separate output nozzle (36) from the discharge orifice (20) of a constant pressure combustor (18) for providing pressure pulses which impinge on the blades (22) of the rotor (14) of the turbine to provide starting torque. The utilization of a separate pulse combustion chamber (24) and discharge orifice (36) having a cross-sectional area different from the discharge orifice (20) of the constant pressure combustor (18) permits efficient pulse operation without adversely affecting the operation of the constant pressure combustor during normal sustained operation of the turbine.

Abstract: On peut réduire le coût d'une structure d'aubes de guidage d'admission variable pour compresseurs rotatifs en réalisant une structure comprenant un logement de compresseur (20) ayant une entrée (24) et un rotor (10) porté par des paliers à l'intérieur du logement (20) grâce à un logement (42) autour de l'orifice d'entrée (24), et comportant un orifice d'entrée (54) s'étendent sur une partie minime de sa périphérie. On peut monter une ou plusieurs aubes (60) dans l'orifice d'entrée (54) pour faire tourbillonner l'air avant qu'il n'entre dans le logement (42).
