A seal assembly and method of directing fluid flow away from a seal. The seal assembly comprises an inner seal member coupled to a rotatable shaft and an outer seal member which is either rotatable or static. The inner seal member has a plurality of knives spaced apart from each other and extending radially away from the shaft. The outer seal member has a rub surface disposed to abut a terminal edge of at least one of the plurality of knives to thereby form a seal. An outer knife of the plurality of knives of the inner seal member extends axially at an angle and is adapted to direct fluid flow away from the seal.

A turbine blade that allows an improvement in torque and power, and a turbine and gas turbine including the same are provided. The turbine blade includes an airfoil having a suction side and a pressure side, a platform coupled to a bottom of the airfoil, and a root protruding downward from the platform and coupled to a rotor disk, wherein the airfoil includes a cooling passage formed therein and a discharge hole connected to an upper portion of the cooling passage to discharge cooling air, and the discharge hole is inclined toward a tip of the turbine blade while extending from an inside to an outside thereof.

A panel for attenuating noise is disclosed comprising a face skin having a first inner surface, a base skin having a second inner surface, a cellular core connected to and forming a plurality of cells between the face skin and the base skin, wherein the cellular core is defined by a cell structure having a plurality of cell walls extending between the face skin and the base skin defining each of the plurality of cells and a septum disposed within each of the plurality of cells, the septum defining an upper chamber proximate the face skin and a lower chamber proximate the base skin, wherein the face skin comprises a plurality of perforations fully through the face skin and in fluid communication with the upper chamber.

A guide vane ring for a turbomachine minimizes a leakage flow that passes through a recess (11) into which a guide vane disk is inserted. It has a guide vane row having a plurality of guide vanes (20), each having a vane airfoil (24) and a vane disk (21), as well as an inner ring (10) having an inner ring surface (12) facing the plurality of guide vanes. Viewed in the direction (R) of a designated primary flow streaming through the turbomachine, the vane disks (21) have a front and a rear surface region (22a, 22b). In a nominal and/or a maximum open position of the guide vanes, the front and/or the rear surface region (22a, 22b) of at least one of the vane disks has an offset (31a, 31b) from the inner ring surface (12) that is radially disposed (relative to a central axis (X) of the inner ring (10)).

An internally cooled component of a gas turbine engine is provided. The component may include a cooling passage at least partially defined by a first wall and a second wall with a first pedestal extending from the first wall to the second wall. The first pedestal may have a chevron geometry. A second pedestal may extend from the first wall to the second wall and also have a chevron geometry. A gap may be defined by the first pedestal and the second pedestal with the gap oriented between the first pedestal and the second pedestal.

An equipment support including at least one attachment including an output shaft, an input gear wheel, the input gear wheel being both rotated by the motor shaft at a main speed and also connected to the output shaft of the attachment in order to rotate it at a determined output speed, an input shaft, rotated by the input gear wheel at a determined input speed, and a reducer with magnetic gears, arranged between the input shaft and the output shaft, such that the input speed is different from the output speed.

A gas turbine engine having a bearing housing with a housing cavity and a shaft rotating about a rotation axis. One or more bearings support the shaft. A housing supporting the bearing and defining a chamber axially adjacent to the bearing. A seal assembly is in the housing between the chamber and an exterior of the chamber. The seal assembly includes a seal supported by the housing and surrounding the shaft so as to define an annular gap between an inner surface of the seal and an outer surface associated to the shaft, the gap defining a part of a sealing path of the seal assembly for air to flow from said exterior into the chamber. An impeller rotates with the shaft and located radially inward of the gap relative to the rotation axis, the impeller oriented to drive oil toward the bearing.

A ring seal apparatus for high temperature sealing includes a first ring including a pair of radial faces and a second ring including a second pair of radial faces, the second ring adapted to coact with the first ring. The first and second rings together define a pair of coacting mating faces. The mating faces are obliquely angled relative to the radial faces, such that each of the coacting mating faces is adapted to seal an interface of the two rings at an angle relative to their substantially parallel radial faces. The pair of coacting rings is adapted to seal a circumferential gap between a pair of components.

An apparatus and method relating to a film-hole of a component of a turbine engine comprising including forming the hole in the component and applying a coating to the component such that the coating fills in portions of the film-hole.

An assembly of at least two members. One of the members supports the other member, the assembly defining an axial direction, a radial direction, and a circumferential direction, an inner member of the at least two members being received radially inside an outer member of the at least two members, wherein the inner member and the outer member am attached to each other by a support arrangement, the support arrangement including at least one floating support assembly as a displaceable coupling between an inner member support point provided at the inner member and an outer member support point provided at the outer member. A displacement of support points in a radial direction results in an interrelated relative displacement of the support points in an axial direction end vice versa.
