HIGH TEMPERATURE HEAT SHIELD ASSEMBLIES
A heat shield assembly adapted for use with gas turbine engines, airframes, and aircraft includes a carrier and a heat-shield tile. The carrier is adapted to couple to the gas turbine engine, airframe, or aircraft. The heat-shield tile includes material different than the carrier and is arranged to cover the carrier to protect the carrier from high-temperature gases surrounding the heat shield assembly.
Heatshield with damper member
A gas turbine engine includes a shaft and a heatshield that circumscribes the shaft. The heatshield defines a cylindrical body that has radially inner and outer sides and extends between first and second axial ends. The heatshield is exclusively supported on the shaft at the first and second axial ends. The heatshield includes at least one seal member on the radially outer side. A damper member is disposed at the radially inner side of the heatshield for attenuating vibration of the heatshield.
CONFORMAL AND FLEXIBLE WOVEN HEAT SHIELDS FOR GAS TURBINE ENGINE COMPONENTS
A heat shielded assembly includes a fuel structure of a combustor of a gas turbine engine and a woven heat shield at least partially conformally surrounding the fuel structure and spaced from an exterior of the fuel structure by a distance where it surrounds the fuel structure. The fuel structure is configured to deliver fuel to the combustor. The woven heat shield comprises a first set of strands, a second set of strands interwoven with the first set of strands, and a weave pattern comprising the first set of strands and the second set of strands. Each strand of the first set of strands extends in a first direction, each strand of the second set of strands extends in a second direction transverse to the first direction, and the first set of strands and the second set of strands are not attached where they intersect in the weave pattern.
Vane with baffle and recessed spar
A vane arc segment includes an airfoil section, a spar, and a baffle. The spar supports the airfoil section and has a leg that extends in an internal cavity of the airfoil section. The leg is spaced from the airfoil wall such that there is a gap there between. The baffle divides the gap into a plenum space between the leg and the baffle and an impingement space between the baffle and the airfoil wall. The baffle has impingement holes directed toward the airfoil wall that connect the plenum space and the impingement space. The impingement space is of substantially uniform thickness and the plenum space is of non-uniform thickness along a portion of the span length of the airfoil section.
HEATSHIELD FOR A GAS TURBINE ENGINE
A heatshield for a gas turbine engine includes a main body having a leading edge, a trailing edge, lateral edges, a first surface and a second surface, the first surface being exposed to a hot working gas in use passing through the gas turbine engine. The main body having an array of cooling channels for conveying a coolant flow, where each cooling channel of the array of cooling channels having a surface. At least one cooling channel of the array of cooling channels includes at least one flow disturbing feature extending from the surface and into the cooling channel.
VANE ARC SEGMENT WITH CONFORMAL THERMAL INSULATION BLANKET
A vane arc segment includes an airfoil piece that defines first and second platforms and a hollow airfoil section that has an internal cavity and extends between the first and second platforms. The first platform defines a gaspath side, a non-gaspath side, and a flange that projects from the non-gaspath side. Support hardware supports the airfoil piece via the flange. There is a conformal thermal insulation blanket disposed on the flange.
METHOD FOR MANUFACTURING AN ENGINE COMPONENT WITH A COOLING DUCT ARRANGEMENT AND ENGINE COMPONENT
The present invention relates to a method for producing an engine component having a cooling duct arrangement which has a plurality of cooling ducts, each having an inflow opening, the inflow openings being arranged according to a predefined pattern in an inflow surface of the engine component, and each cooling duct opening into a recess in a wall of the engine component, along which wall a cooling film is to be formed. According to the invention, the pattern is formed in at least one subregion of defined size of the inflow surface, from a plurality of identical isosceles triangles, which are defined by a minimum spacing (k) and by a mean diameter (a) of the inflow openings correlating to the minimum spacing (k). This procedure reduces the complexity of the design process.
Turbocharger device
A turbocharger device includes a case having a turbine portion and a bearing portion connected to and extending from the turbine portion. The turbine portion defines a cavity that houses a turbine wheel and receives exhaust gas that rotates the turbine wheel. The bearing portion houses a shaft connected to the turbine wheel. The bearing portion has a radial thickness between an exterior surface and an interior surface. The interior surface defines a central channel. The bearing portion holds a bearing system that supports the shaft within the central channel. The bearing portion includes a lattice structure within the radial thickness. The lattice structure is a repeating three-dimensional array of frame segments connected to one another at junctions. The lattice structure engages a turbine back wall that is located between the turbine portion and the bearing portion. The lattice structure defines interstitial spaces between the frame segments.
Vane arc segment formed of fiber-reinforced composite
A method of fabricating an airfoil fairing for a vane arc segment includes providing a mandrel that necks down through a mandrel neck portion, providing fiber plies around the mandrel to form a tube that defines at least a portion of an airfoil profile of an airfoil section of an airfoil fairing, the fiber plies following the mandrel neck portion such that the tube has a corresponding tube neck portion that necks down to a collar, and removing the mandrel from the tube.
Nozzle ring for a turbocharger
The invention relates to a nozzle ring (10) for a radial turbine. The nozzle ring comprises a rotationally symmetrical, disk-shaped main body (11) with a central opening (12) for the leadthrough of a shaft (20). Furthermore, the nozzle ring comprises guide blades (14) which are arranged in a circumferential direction in a radially outer region of the main body (11) and which are designed to direct exhaust gases onto rotor blades (31) of a turbine wheel (30). The main body (11) of the nozzle ring is designed to, in the installed state, form a heat shield between a bearing space (40) of a bearing housing (41) and a turbine space (50).
