摘要： In accordance with one aspect of the present invention, a combustor is disclosed having three separate domes, each dome having disposed therein a plurality of circumferentially spaced mixers for uniformly mixing air and fuel. The combustor utilizes a high percentage of the total available combustion air at the dome area in order to maintain a lean mixture of air and fuel during all levels of engine output. Besides providing an unobstructed area in the diffuser dump region upstream of the mixers for the combustion air, sealing means is included to prevent cooling air from entering the combustion chamber until downstream of the primary combustion zone. Heat shields having radial centerbodies are also included between each dome to isolate each primary combustion zone.

摘要： An annular combustor with an air fuel mixer is disclosed including a plurality of mixing tubes having a forward end and an exit end, wherein a longitudinal axis through the exit end for each mixing tube is at both an axial angle and a radial angle to the centerline axis of the mixer. A fuel injector for providing fuel to the forward end of each mixing tube, a fuel manifold in flow communication with each of the fuel injectors, and a fuel supply and control means are provided. High pressure air from a compressor is injected into the mixing tubes and fuel is injected into the mixing tubes from the fuel injectors, wherein the high pressure air and the fuel is uniformly mixed therein so as to produce minimal formation of pollutants when the fuel/air mixture is exhausted out the downstream end of the mixing tubes into the combustor and combusted. The mixing tubes preferably impart a swirl to the fuel/air mixture as it exits into the combustor.

摘要： A double annular combustor having concentrically disposed inner and outer annular combustors is provided with inner and outer domes. A one-piece cowl is provided upstream of the inner and outer domes in order to form a high pressure region. The one-piece cowl has an inner annular portion, an outer annular portion, and a radial middle portion connecting the inner and outer annular portions. The inner and outer annular portions include scalloped areas therein to facilitate insertion and removal of fuel tubes and nozzles. The cowl middle portion includes a shield to isolate the scalloped areas and the fuel tube from the high pressure region, thereby preventing leakage of air flow and consequential pressure loss from the high pressure region.

摘要： A friction-damped combustor cowl is formed of first and second plies of sheet material of mating, generally annular configuration defining a central cowl axis and of axially elongated and aerodynamically contoured configuration have respective fore end portions which are curled to form a cowl leading edge of arcuate cross section and corresponding fore edges which are integrally joined, and respective aft end portions which define a cowl trailing edge and corresponding aft edges which are integrally joined. Surface contact of the contiguous surfaces of the laminated and mating first and second plies provides vibration damping under normal operating conditions in an alternative and combustor cowl, a spring element is received and maintained under compression within the curled leading edge of the combustor cowl and maintains a resilient biasing force maintaining surface contact between the spring element and the interior surface of the curled leading edge, thereby maintaining frictional surface contact and requisite vibration damping under normal operating conditions.

摘要： A mixer arrangement for a bypass type gas turbine engine is disclosed. The mixer is convoluted and generally annular and defines radially and axially extending first and second chutes adapted to receive, respectively, a hot gas stream from the engine core and a cooler gas stream from the fan duct. A pre-mixer is disposed upstream of the mixer and is also convoluted and is aligned in flow communication with the second chutes of the mixer such that the hot gas stream received by the pre-mixer is mixed with the cooler fan air stream received by the second chutes to raise the temperature of the fan air entering an afterburner section of the engine.

摘要： A carburetion assembly including flow control means is provided for controlling a discharge spray angle of a fuel and air mixture thereof. According to one embodiment of the present invention, the flow control means can comprise a plurality of circumferentially spaced apertures in a shroud member which are effective for providing a control portion of compressor airflow in a downstream, axial direction from a swirler stage of the swirler assembly. The apertures provide a predetermined amount of airflow circumferentially about the fuel and air mixture for constraining the mixture and controlling the discharge spray angle thereof.

摘要： In a turbofan jet engine, having a circumferentially rotatable mixer segment capable of orienting the afterburner ignitors and flameholders into the path of either the exhaust gases or bypass air, a fuel-air transfer apparatus for capturing, transporting and the releasing of an enriched fuel-air concentration from the fuel spray bars, on the stationary structure of the jet engine, to the afterburner ignitors and flameholders rigidly attached at the rear of the rotatable segment of the mixer. The enriched fuel-air mixture is transported between a location of reliable fuel availability, through a region of highly turbulent gas flow and is thereafter released while still in an enriched concentration immediately upstream of the ignitors and flameholders, facilitating ignition and sustained operation of the afterburner. The transfer of the fuel-air mixture with the exhaust gases in a confining apparatus precludes the necessity for transferring fuel, by flexible attachment or other means, between the stationary jet engine structure and the rotatable segment of the mixer, upon which the ignitors and flameholders are mounted, while insuring an appropriate fuel-air mixture for ignition and operation of the afterburner.
