Sealing arrangement with vent for an engine component with a service port
An apparatus of an aircraft engine having lubricated moving components is provided. The apparatus comprises a housing having a lubricant cavity for receiving lubricant and a service port cavity, the housing defining a selectively openable service port for accessing the service port cavity. A shaft is mounted for rotation about a rotational axis to the housing. A seal is mounted about the shaft forming a partition between the lubricant cavity and the service port cavity. A vent channel extends between the lubricant cavity and the service port cavity.
Equipment drive gearbox in a turbomachine
A drive gearbox for turbomachine equipment, the drive gearbox having a main shaft intended to be rotationally connected to a power transmission shaft of a turbomachine. The main shaft has at least one bevel gear rotationally driving at least one piece of equipment. The gearbox has gear set with cylindrical gearwheels that have an input connected to the rotational drive to the main shaft and a plurality of outputs each intended to drive a piece of equipment. The gear set extends over an angular sector and the outputs are angularly spaced apart along the angular sector.
Acoustic treatment panel for a turbojet engine
An acoustic absorption cell including a bottom wall extending in a plane orthogonal to an axial direction, an enclosure including a first axial end secured to the bottom wall, and an acoustic horn extending inside the enclosure between a first opening of the horn and a second opening of the horn smaller than the first opening, the horn being secured to a second axial end of the enclosure opposite the first axial end, and the first and second openings of the horn each extending in a plane orthogonal to the axial direction. The horn includes at least one retaining arm protruding from the horn inside the enclosure and fixed to the bottom wall or to the enclosure.
ANNULAR COMPONENT FOR SUPPORTING A TURBINE ENGINE BEARING
A component (1, 2) for supporting at least one bearing (3) for a turbine engine (10) comprising: two coaxial walls, internal (4) and external (5) walls respectively, defining a gas flow vein (6) between them and interconnected by a row of arms (7); an external ferrule (50) comprising an internal peripheral edge (51) connected to the external wall (5) and an external peripheral edge (52) connected to an external mounting flange (53); an internal ferrule (40) comprising an external peripheral edge (41) connected to the internal wall (4) and an internal peripheral edge (42) comprising an internal mounting flange (43); at least one of the ferrules (4, 5), which at the peripheral edge (41, 51) thereof is connected to the corresponding wall (4, 5), having a general shape which is corrugated about an axis (X-X) of the component (1, 2).
METHOD FOR PRODUCING A CASING FOR AN AIRCRAFT TURBINE ENGINE
Method for manufacturing a casing of an aircraft turbomachine, the casing including an annular shell extending about an axis A and made of a composite material including fibres that are woven and immersed in a resin, the annular layer including an abradable material arranged inside the shell, and covering a first inner annular surface of an intermediate section of the shell, the method including a step of gluing the layer on the first surface, during which the casing is heated and compressed by a system that is present at least partially inside the casing, wherein, prior to the heating and compression of the casing, a forming tool is mounted inside the casing and is made of two rings.
Cooling hole filter configuration
A gas turbine component includes a turbine component having an outer wall and an internal cooling passage; a cooling air supply hole through the outer wall in fluid communication with the internal cooling passage; and a filter mound disposed over the cooling air supply hole. The filter mound includes a filter mound wall projecting from the turbine component and defining an interior of the filter mound. At least one hole in the filter mound wall extending through the filter mound wall is configured to permit cooling air supply to pass therethrough while blocking debris from passing through the interior of the filter mound and clogging the cooling air supply hole in fluid communication with the internal cooling passage. The turbine component and the filter mound are formed during manufacturing of the turbine component.
Turbine nozzle with compliant joint
A turbine nozzle for a gas turbine engine includes an outer endwall, and an inner endwall spaced apart from the outer endwall. The turbine nozzle includes at least one airfoil coupled between the inner endwall and the outer endwall, and a compliant joint defined in at least one of the outer endwall and the inner endwall. The compliant joint includes at least one partially-fused seal that is configured to restrict a flow of fluid through the at least one of the outer endwall and the inner endwall and to form a slip-joint above a predetermined threshold stress. The slip-joint is configured to maintain a radial position of the at least one of the outer endwall and the inner endwall.
Quench aperture body for a turbine engine combustor
An assembly for a turbine engine includes a combustor wall. The combustor wall includes a shell, a heat shield and an annular land. The heat shield is attached to the shell. The land extends vertically between the shell and the heat shield. The land extends laterally between a land outer surface and an inner surface, which at least partially defines a quench aperture in the combustor wall. A lateral distance between the land outer surface and the inner surface varies around the quench aperture.
VACUUM PUMP AND CONNECTION PORT USED IN VACUUM PUMP
Provided are a vacuum pump which can be reduced in size without reducing exhaust performance, and a connection port which is used in the vacuum pump. The connection port which connects the vacuum pump and an auxiliary pump includes an oval first opening connectable to the vacuum pump and a circular second opening connectable to the auxiliary pump, and a diameter dimension of the first opening is set to be smaller than a diameter dimension of the second opening in an axial direction of the vacuum pump.
Turbine ring assembly having indexed flanges
A turbine ring assembly includes ring segments forming a turbine ring and a ring support structure, each segment having a part forming an annular base with, in the radial direction, an inner face and an outer face from which project a first and a second hooking tab, the structure including a shroud from which project a first and a second radial flange between which are retained the first and second tabs, a first annular flange made of one part and a second annular flange disposed upstream of the ring.
