A seal assembly for a gas turbine engine (10) includes an engine static structure (30). First and second members fluidly separate cavities (52, 54, 56, 58) from one another. A seal assembly (46, 48) is captured by the engine structure (30). The seal assembly (46, 48) includes a carrier (70) and a seal (82) that engages the first member (88). The second member is captured by the carrier (70).
摘要:
Mechanical fastening system (10) for rotating or stationary components (1) such as turbine or compressor blades on a rotor or a shaft or a casing, respectively comprising a circumferential mounting groove adapted for receiving root sections (2) of said rotating or stationary components (1) as well as intermediate fastening components (3) for fixation of said components (1) in equidistance positions, whereby said intermediate fastening components (3) comprise at least an upper platform (31) and at least a side plate (32) having a groove (4) for mounting on said rotor, whereby said intermediate fastening components (3) are made of a plurality of distinct parts (31, 32, 33) of different materials from which at least one clamping part (33) is made of or comprises a shape memory alloy or similar material having a pseudo-elasticity behavior.

A retainer plate is provided for retaining a dovetail root of a fan blade of a gas turbine engine in a corresponding axially-extending slot in the rim of a fan disc. In use, the plate locates in a cavity formed at an end of the slot such that a first side of the plate is arranged for contact with an axial end face of the dovetail root and an opposite second side of the plate is arranged for contact with an abutment surface of the cavity to limit axial movement of the root along the slot. The retainer plate is formed from fibre-reinforced composite material, at least a portion of the composite material being reinforced by 3D-woven fibre tows.

An assembly for use in a gas turbine engine includes an inner diameter (ID) shroud having a plurality of ID slots and an outer diameter (OD) shroud having a plurality of OD slots and positioned radially outward from the ID shroud. A plurality of stator airfoils extend from the ID shroud to the OD shroud. Each of the stator airfoils is positioned at least partially in one of the ID slots and is positioned at least partially in one of the OD slots. A bumper is positioned proximate a first end of each of the stator airfoils so as to limit movement of the stator airfoils in a radial direction.
摘要:
A mechanism for use in a gas turbine engine has a cover plate (15), a rotor disk (10), a first slot (115) in the cover plate (15), a second slot (120) in the rotor disk (10), a first finger (130) in the cover plate (15) extending through the second slot (120), and a second finger (145) in the rotor disk (10) extending through the first slot (115). The first finger (130) and the second finger (145) form a channel (135) and a holder (140) is disposed in the channel (135) for locking the rotor disk (10) and the cover plate (15) together.
摘要:
A gas turbine engine exhaust panel mounting system comprising a panel (102), a casing (104) and an attachment assembly (100) for removably connecting the panel (102) to the casing (104) comprises a retaining portion (110), a clamping portion (120), and a 'C'-shaped connecting link (130). The connecting link (130) has a first attachment portion (132) and an opposite second attachment portion (134) with the first (132) and second attachment portions (134) being connected to one another by a centre portion (136). Each of the first (132) and second attachment portions (134) is substantially parallel to one another and extends in the same direction from respective ends of the centre portion (136). The first attachment portion (132) is fixedly connected to the casing (104) by the clamping portion (120), and the second attachment portion (134) is slidingly connected to the panel (102) by the retaining portion (110).
摘要:
The invention relates to a turbine blade (10), comprising a blade (11) having a front edge (13) and a rear edge (14), which blade transitions by means of a shaft (15) into a blade root (16) designed for fastening the turbine blade (10), and comprising a platform (17), which is arranged at the lower end of the blade (11) in order to bound a flow channel, wherein the platform (17) is designed as a separate component and can be connected to the blade (11) in a form-fit manner. Flexible application is achieved in that the platform (17) is composed of several individual platform elements (17a, 17b), which enclose the blade (11) in the assembled state.
