摘要： A stator assembly (10) usable in a gas turbine engine (12) and configured to restrain inner and outer endwalls (14, 16) to limit deflection and prevent clearance loss relative to adjacent blade rotor disks (18) is disclosed. The stator assembly (10) may be formed from a plurality of stator vanes (20) with inner and outer endwalls (14, 16) that are coupled together with a first radially outer tie bar (22). In at least one embodiment, first and second radially outer tie bars (22, 24) may form first and second stator vane segments (26, 28) that together form the circumferentially extending stator assembly (10). The inner and outer endwalls (14, 16) may be coupled together with one or more circumferentially extending alignment pins (30) that limit deflection. The stator assembly (10) may include one more deformable seals (52) extending radially inward from the inner endwall (14).

摘要： A stator vane segment (10) including a connection system (12) that enables stator vane (14) alignment while enabling an individual stator vane (14) to be replaced is disclosed. The stator vane connection system (12) may include a radially extending inner support (26) extending from a stator vane (14), whereby the inner support (26) is secured to forward and aft inner rings via a removable, inner axial bolt (22). The stator vane connection system (12) may include one or more first inner pins (24) that aligns the stator vane (14) and is positioned within the portion of the inner support (26) of the stator vane (14) to which one or more inner axial bolts (22) are attached. The stator vane connection system (12) may include one or more first outer alignment pins (28) that aligns the stator vane (14) and is positioned within a portion of the outer diameter platform (48) of the stator vane (14), whereby the first outer alignment pin (28) aligns the stator vane (14).

摘要： The invention relates to a blade arrangement (40) having a blade carrier (56) and having a retaining groove (58) arranged in said blade carrier, which retaining groove has projections (62) extending along the side walls (60) thereof so as to form undercuts (64) and into which retaining groove a number of blades (25, 27) are inserted so as to form a blade ring of a turbomachine, wherein each blade (25, 27) has, in addition to a blade airfoil (48) and for fastening purposes, a blade root (50) which engages into the undercuts (64), and each blade is pressed against the projections (62) by an element (46) arranged between a blade root underside (68) and a groove base (70) of the retaining groove (58). To specify a particularly secure, reliable, durable and low-wear fastening which permits particularly simple assembly and disassembly, it is provided that each element (46) is of plate-like form and has, in the projection of the blade airfoil (48) in the direction of the groove base (70), at least one bead (52, 55), arranged beneath the blade airfoil (48), for imparting a pressing action, and in the longitudinal direction of the retaining groove (58), only part of the blade root (50) which said element presses against is covered.
