  • A gas turbine engine ducting arrangement (10), including: an annular chamber (14) configured to receive a plurality of discrete flows of combustion gases originating in respective can combustors and to deliver the discrete flows to a turbine inlet annulus, wherein the annular chamber includes an inner diameter (52) and an outer diameter (60); an outer diameter mounting arrangement (34) configured to permit relative radial movement and to prevent relative axial and circumferential movement between the outer diameter and a turbine vane carrier (20); and an inner diameter mounting arrangement (36) including a bracket (64) secured to the turbine vane carrier,more » wherein the bracket is configured to permit the inner diameter to move radially with the outer diameter and prevent axial deflection of the inner diameter with respect to the outer diameter.« less
  • A combustion chamber for a gas turbine, in particular for motor vehicles, with an atomizer nozzle for the fuel fed to a prechamber, in which the inlet cross section for the primary air is changed by the longitudinal movement of a deflection member extending through the inlet opening of the combustion chamber. The deflection member serves as a flame holder for the stabilization of the combustion in the primary air zone while the air-atomizing nozzle is constructed ring-shaped and is provided with swirl slots in such a manner that the mixture of the fuel and of the atomizing air entersmore » as an annular jet the primary air inlet channel, impinges approximately perpendicularly onto the primary air flow, penetrates the same and uniformly mixes with the same on its way to the inlet into the primary zone. The quantity of the primary air to be supplied is thereby automatically adjustable.« less
  • This patent describes a method of operating a gas turbine engine in an aircraft, the engine having fuel nozzles disposed of a combustion chamber which regions are in flow communication with each other, the engine being operative at an idle power condition and a cruise power condition. It comprises: flowing fuel from all the nozzles of the fuel nozzles at the idle power condition and the cruise power condition; operating the combustion chamber with a local fuel/air ratio in a first region of the combustion chamber which is richer than the local fuel/air ratios in other regions of the combustionmore » chamber at the idle power condition by flowing fuel from all of the fuel nozzles of the fuel nozzles with flow through at least one of the nozzles in communication with the first region being greater than the flow through the remainder of the nozzles to flow more fuel to the first region than to other regions of the combustion chamber; operating the combustion chamber with the same local fuel/air ratio in the first region of the combustion chamber and remaining regions of the combustion chamber at the cruise power condition by flowing the same amount of fuel to all regions of the combustion chamber by flowing fuel from all of the fuel nozzles of the fuel nozzles at the cruise power condition such that the flow through all of the fuel nozzles is the same.« less
  • A gas turbine has a combustion chamber of toroidal configuration that includes separation structure dividing the combustion chamber into an annular primary zone and an annular dilution zone. Injection of compressor discharge air into the primary zone sets up a toroidal recirculation pattern of generally circular cross-sectional configuration. Fuel slinger structure at the inner periphery of the primary zone has a generally cylindrical surface for receiving and distributing fuel in a thin sheet for discharge in a radially outward direction as minute droplets towards the center of the toroidal recirculation pattern. The radial flow of the fuel droplets interacts withmore » the toroidal recirculation pattern and provides intimate mixing of fuel and air, and resulting efficient combustion within the primary zone. The resulting combustion product flows from the primary zone past the separation structure into the dilution zone. Compressor discharge air injected into the dilution zone dilutes the products of combustion from the primary zone.« less
  • A gas turbine combustion chamber is described having a wall with an inner surface exposed to the combustion chamber flame, and a coating of a catalytic material on the surface over a large enough area thereof to cause reignition of the fuel-air mixture after flame-out.
