  • Patent number: 11613996
    Abstract: A pre-swirl nozzle carrier for a gas turbine engine, includes: a wall having front and rear sides, and a multiplicity of pre-swirl nozzles formed in the wall and which each have a flow passage, wherein the flow passage has an inlet opening at the front side and an outlet opening at the rear side. The flow passages are provided and designed to discharge air, which has flowed in via the inlet opening, with swirl from the outlet opening. It is provided that the inlet opening is surrounded by a periphery which, at least in certain sections, has a region with a convex curvature adjacent to the flow passage and has a region with a concave curvature adjacent to said region with a convex curvature. The invention furthermore relates to a method for producing a pre-swirl nozzle in a pre-swirl nozzle carrier.

  • Patent number: 11397123
    Abstract: The proposed solution concerns in particular an engine, with at least two valve devices for controlling bleed air in dependence on an operating state of the engine, the at least two valve devices in each case being adjustable between an open position and a closed position. A flow space is provided for at least one fluid flow occurring in the flow space in dependence on a position of the at least two valve devices. Arranged in the flow space is at least one fluid sensor, by means of which at least one position of at least one of the at least two valve devices can be determined on the basis of the fluid in the flow space.

  • Publication number: 20200141262
    Abstract: The proposed solution relates in particular to an engine having at least one flow-guiding element within the engine, via which, during malfunction-free operation of the engine, at least one target flow of fluid is conducted along a first flow direction and via which, in the event of a malfunction within the engine, a fault flow of fluid of a higher temperature than the fluid of the target flow is conducted along a second flow direction, which differs from the first flow direction, and at least one temperature sensor which is situated in a flow path both of the target flow and of the fault flow.

  • Patent number: 10619490
    Abstract: A turbine rotor blade arrangement for a gas turbine, having a turbine disc and a turbine rotor blade ring that comprises a plurality of rotor blades. The turbine disc has disc channels for providing air, wherein a disc channel respectively ends in a discharge hole in the area of a blade root reception area. The rotor blades have cooling air channels for cooling the rotor blades. In the blade root or between the blade root and the blade root reception area, an air channel is formed via which sealing air is discharged that is fed in from the disc channel. It is provided that the blade root comprises a deflection device that is provided and is configured for the purpose of partially deflecting air exiting the disc channel in the direction of the air channel. Another embodiment of the invention relates to a method for the provision of sealing air in a turbine rotor blade arrangement.
