    Abstract: Vibration damping is important with regard to such components as hollow turbine blades in gas turbine engines. Traditionally damping has occurred through damping elements secured at the root or tip of such blades. Such damping is not optimised and results in potential problems with wear in operational life. By providing a tube of deformable material which can be located within a hollow cavity it is possible to provide an element which through friction engagement can absorb vibration energy and therefore damp such vibration. The tube incorporates a number of cuts and/or grooves in an appropriate pattern in order to define a deformation profile once the tube is expanded in location. The tube is secured in position internally upon an expandable element which is typically an inflatable device. Once in position the tube is retained in its expanded deformable profile and the engagement between the tube and the hollow cavity wall surface results in energy absorption through vibration episodes. It is also possible to provide a tube formed from a shape memory alloy which will expand of its own right in location to engage the hollow cavity wall surfaces for energy absorption during vibration episodes.

    Abstract translation: 振动阻尼对于诸如燃气涡轮发动机中的中空涡轮叶片的部件是重要的。 传统的阻尼是通过固定在这种叶片的根部或尖端处的阻尼元件发生的。 这种阻尼没有被优化,并且在使用寿命中导致潜在的磨损问题。 通过提供可以位于中空腔内的可变形材料管,可以提供通过摩擦接合可以吸收振动能量并因此减弱这种振动的元件。 该管以合适的图案包括多个切口和/或凹槽,以便一旦管在位置上扩展就能限定变形曲线。 管内部固定在可膨胀元件上,该可膨胀元件通常是可充气装置。 一旦就位,管被保持在其膨胀的可变形轮廓中,并且管与中空腔壁表面之间的接合导致通过振动发生的能量吸收。 还可以提供一种由形状记忆合金形成的管,其将在其位置上自身扩张以接合中空腔壁表面,以在振动发生期间吸收能量。

    Abstract: An airfoil component and method for producing the component. The component has root and airfoil portions, the latter having an airfoil tip and oppositely-disposed concave and convex surfaces that converge at leading and trailing edges of the airfoil portion. The airfoil portion has at least one stiffener between first and second walls thereof that define the concave and convex surfaces, respectively. The stiffener defines multiple internal cavities within the airfoil portion that extend in the span-wise direction of the airfoil portion. A polymeric material fills at least one of the internal cavities and is bonded to the airfoil portion only at an extremity of the internal cavity nearer the root portion, and not to the stiffener or to the first and second walls of the airfoil portion, to define an internal damping member that provides a vibratory damping effect to the airfoil portion.
