摘要： A securing arrangement 32 for securing an actuating lever 20 to a spindle 14, for example a spindle 14 of a variable inlet guide vane 10 in a gas turbine engine, comprises a fastening formation 38 rotatably co-operable, in use, with a corresponding fastening formation 30 on the spindle 14. The securing arrangement 32 is rotatable relative to the spindle 14 to a securing position in which the respective fastening formations 30, 38 co-operate so that the securing arrangement 32 secures the actuating lever 20 to the spindle 14. The securing arrangement 32 includes anti-rotation means 42, preferably in the form of anti-rotation tabs 44, for preventing rotation of the securing arrangement 32 from the securing position.

摘要： A vane arrangement for a compressor of a gas turbine engine comprises a plurality of circumferentially arranged vanes, a plurality of levers and a control ring. Each vane comprises a fixed upstream portion secured to a casing and a movable downstream portion pivotally mounted to the casing. The movable portion of each vane is pivotally mounted at the upstream end of the movable portion adjacent the fixed portion of the respective vane. The movable portion of each vane has a spindle extending through an aperture in the casing. Each aperture in the casing has an elongate shape in cross-section and each aperture has a bush arranged within the aperture and around the spindle to fill the elongate shaped aperture. The downstream end of the fixed portion of each vane has substantially the same shape as the upstream end of the movable portion of the respective vane.

摘要： An axial flow compressor (16) comprises a plurality of variable stator vanes (32) circumferentially spaced apart and extending radially. Each variable stator vane (32) is rotatably mounted on a compressor casing (28). A control ring (38) surrounds the compressor casing (28). Each variable stator vane (32) is connected to the control ring (38) by a respective one of a plurality of operating levers (40) and the control ring (38) is spaced from the compressor casing (28) by a clearance. A plurality of bimetallic strips (50) are arranged circumferentially and are positioned radially between the control ring (38) and the compressor casing (28) and the bimetallic strips (50) control the clearance between the control ring (38) and the compressor casing (28) whereby any error of the variable stator vane (32) angular position is reduced. Each bimetallic strip (50) extends radially outwardly from the compressor casing (28) towards the control ring (38). Each bimetallic strip (50) comprises a first metal strip (52) bonded to a second metal strip (54) and the first metal strip (52) has a different coefficient of thermal expansion than the second metal strip (54).

摘要： An injection-molded thermoplastic mini-platform is adhesively bonded, in use, to the aerofoil surfaces of a fan blade in a gas turbine engine. The mini-platform is divided into a number of leaves, to increase its flexibility, and ribs beneath the leaves provide additional stiffness in the radial direction. In the event that a fan blade is released in operation, the mini-platform is designed to detach from the blade and/or to break apart, so that damage to other components of the engine is minimized.

摘要： A seal (30) is provided for reducing the gap between alternate wall members (20) and adjacent blades (14) that are arranged circumferentially in a rotor (12). The seal (30) has a flange portion (36), which is inclined radially inward. The flange portion (36) of the seal (30) is in the form of rubber bellows (32) which have a cavity (34) therein. In operation the flange portion (36) of the seal (30) is deflected radially outwards by centrifugal forces acting thereon. The seal (30) is open at one end to allow air compressed by the rotor (12) to pass into the cavity (34) and inflate the seal (30). Inflation of the seal (30) ensures that the gap between the edge (26) of the wall member (20) and the blade (14) is filled. A good seal is thus maintained throughout operation of the rotor (12) and prevents the air in void (28) passing into the blade passage.
摘要翻译：设置有用于减小在转子（12）周向布置的替代壁构件（20）和相邻叶片（14）之间的间隙的密封件（30）。密封件（30）具有径向向内倾斜的凸缘部分（36）。密封件（30）的凸缘部分（36）是橡胶波纹管（32）的形式，其中有空腔（34）。在操作中，密封件（30）的凸缘部分（36）通过作用在其上的离心力径向向外偏转。密封件（30）在一端敞开，以允许由转子（12）压缩的空气进入空腔（34）并使密封件（30）膨胀。密封件（30）的充气确保了壁构件（20）的边缘（26）和叶片（14）之间的间隙被填充。因此，在转子（12）的整个操作过程中保持良好的密封，并且防止空气（28）中的空气进入叶片通道。
