摘要： An integrally bladed rotor is constructed from a plurality of layers of organic matrix composite material wound together in a spiral fashion to form the disc portion of the rotor, and at each rotor blade position at least the outermost one of the layers is turned substantially radially outwards from the periphery of the rotor disc to form a blade. Each blade is finished with further pieces of organic matrix composite material bonded into position on the. An encircling blade tip shroud may be formed by further layers of material wound around the tips of the blades in conjunction with closed loop inserts in the spaces between blades.

摘要： A damped airfoil structure comprises an airfoil having a first wall and a second opposing wall, and vibration damping means for damping relative movement of the first and second wall. The damping means comprises at least two cooperating damping elements, a first damping element mounted to the first wall of the structure and a second damping element mounted to the second wall of the structure.

摘要： A component such as a blade for use in a gas turbine engine comprises a body 2 formed from outer panels 8, 10 defining an internal cavity 12. A damping element 14 is provided in the cavity 12 and is secured at one end between the panels 8, 10 at one end of the body 2, for example adjacent the root of the blade. Damping material fills the cavity 12 and so extends between the damping element 14 and the panels 8, 10. Vibration induced in the blade causes relative movement between the body 2 of the blade and the damping element 14, causing energy loss in the damping material which damps the vibration.The components 8, 10, 14 may be secured by a diffusion bonding process.
摘要翻译：诸如用于燃气涡轮发动机的叶片的部件包括由限定内部空腔12的外部面板8,10形成的主体2。阻尼元件14设置在空腔12中，并且一端固定在主体2的一端处的面板8,10之间，例如与叶片的根部相邻。阻尼材料填充空腔12并因此在阻尼元件14和面板8,10之间延伸。在叶片中引起的振动导致叶片的主体2和阻尼元件14之间的相对运动，从而导致阻尼材料中的能量损失，从而阻止振动。部件8,10,14可通过扩散粘合工艺来固定。

摘要： A method and system for accepting or rejecting a curved surface of a body under evaluation involves conducting a comparison between the curvature of a surface profile for the surface under evaluation and higher and lower curvature tolerance boundaries. The higher and lower curvature tolerance boundaries are determined from a desired surface profile. The curvature at a plurality of locations on the curve profile under evaluation may be defined with reference to a geometric variable for said curved surface and may be plotted on a graph. The higher and lower curvature tolerance boundaries may also be plotted on the graph so as to determine whether the plot of curvature for the surface under evaluation falls within the bounds of the higher and lower tolerance boundaries.
摘要翻译：用于接受或拒绝正在评价的身体的曲面的方法和系统包括进行被评估表面的曲率曲率与较高和较低曲率公差边界之间的比较。根据期望的表面轮廓确定较高和较低的曲率公差边界。在评估曲线轮廓上的多个位置处的曲率可以参考所述弯曲表面的几何变量来定义并且可以绘制在图上。也可以在曲线图上绘制较高和较低的曲率公差边界，以便确定被评估表面的曲率曲线是否落在较高和较低公差边界的范围内。
