摘要： A seal for stator vane segments within a gas turbine engine is provided which includes an axial member and an end member. The axial member includes a central portion and at least one axial joint element extending out from the central portion. The central portion has across-section which includes a pair of substantially u-shaped circumferential ends connected by an arcuate midsection. The axial joint element transitions from the arcuate midsection to a substantially flat end. The end member includes an end joint element attached to a radial portion. The axial and end joint elements contact each other to prevent leakage therebetween, and also sidably cooperate with each other to accommodate misalignment between the axial member and the end member.

摘要： A stator vane assembly for a gas turbine engine includes a plurality of stator vane segments and fasteners. Each stator vane segment includes an inner radial platform, an outer radial platform, at least one airfoil extending between said platforms, and a first mounting flange extending radially outward from said outer radial platform. Each first mounting flange is aligned with a second mounting flange extending radially inward from an outer case surrounding the stator vane assembly. Each fastener includes a bolt extending through the first and second mounting flanges, a nut for threaded engagement with the bolt, and apparatus for preventing vibration of the fasteners.

摘要： A stator vane assembly for a gas turbine engine is provided which includes a plurality of stator vane segments and a seal ring. Each stator vane segment has an outer platform, an inner platform, and an airfoil extending between the platforms. The stator vane segments collectively form an annular structure. The seal ring includes an abradable bearing pad which extends out from an axial surface of the body of the seal ring. The seal ring is attached to a non-rotating member within the engine, positioned in close proximity to the stator vane segments. Contact, and consequent friction, between the individual stator vane segments and the abradable bearing pad causes the abradable bearing pad to abrade, thereby creating a sealing surface reflective of the opposing stator vane segments in contact with the abradable bearing pad.
摘要翻译：提供了一种用于燃气涡轮发动机的定子叶片组件，其包括多个定子叶片段和密封环。每个定子叶片段具有外平台，内平台和在平台之间延伸的翼型件。定子叶片段共同形成环形结构。密封环包括从密封环的主体的轴向表面延伸的可磨损的轴瓦。密封环附接到发动机内的非旋转构件，其定位成紧邻定子叶片段。在各个定子叶片段和可磨损的轴瓦之间的接触和随之而来的摩擦使得可磨损的轴承垫磨损，从而产生反映与可磨损轴承瓦块接触的相对的定子叶片段的密封表面。
