    • Airfoil arrangement comprising a sealing element made of metal foam An airfoil arrangement (100) for a gas turbine comprises a first airfoil device (110), a second airfoil device (120) and a sealing element (210). The first airfoil device (110) comprises a first root section (112) with which the first airfoil device (110) is mountable to an airfoil disc (200). The first root section (112) comprises a first platform (214), a first leading edge side (215) and a first trailing edge side (213). The first root section (112) has a first cavity (111) which is partially surrounded by the first platform (214), the first leading edge side (215) and the first trailing edge side (213). The second airfoil device (120), which has generally the same structural elements as the first airfoil device (110), comprises a second cavity, wherein the first airfoil devices (110, 120) are mountable to the airfoil disc (200) such that the first root section (112) adjoins to the second root section and the first cavity (111) and the second cavity form a common cavity. The sealing element (210) comprising a metal foam is located inside the common cavity such that the sealing element (210) covers a gap (101) between the first root section (112) and the second root section.
    • 包括由金属泡沫制成的密封元件的翼型装置用于燃气轮机的翼型装置(100)包括第一翼型装置(110),第二翼型装置(120)和密封元件(210)。 第一翼型装置(110)包括第一根部(112),第一翼型装置110可安装到翼型盘200。 第一根部分(112)包括第一平台(214),第一前缘侧(215)和第一后缘侧(213)。 第一根部(112)具有由第一平台(214),第一前缘侧(215)和第一后缘侧(213)部分地包围的第一空腔(111)。 具有与第一翼型装置(110)大致相同的结构元件的第二翼型装置(120)包括第二空腔,其中第一翼型装置(110,120)可安装到翼型盘(200),使得 第一根部分(112)与第二根部部分相邻,并且第一腔体(111)和第二腔体形成共同的空腔。 包括金属泡沫的密封元件(210)位于公共空腔的内部,使得密封元件(210)覆盖第一根部(112)和第二根部之间的间隙(101)。

    • A fan blade fragment containment assembly for a gas turbine engine having a fan case surrounding the fan and having a circumferential axially extending blade fragment impact zone. An inner relatively slack or low tension deformable layer of Kevlar TM or Zylon TM fabric is mounted to the fan case outer surface and envelopes the impact zone. A compressible (ex. metal foam or honeycomb) layer is mounted on an outer surface of the deformable layer. A friction reduction layer of Teflon TM is mounted on an outer surface of the compressible layer and an outer relatively taut higher tension containment layer of Kevlar TM or Zylon TM fabric is mounted on an outer surface of the friction reduction layer. The friction reduction layer enhances the distribution of impact forces about the circumference of the compressible layer by reducing local shear stresses between the compressible layer and the containment layer.
    • 一种用于燃气涡轮发动机的风扇叶片碎片容纳组件,其具有围绕所述风扇且具有周向轴向延伸的叶片碎片冲击区的风扇壳体。 Kevlar TM或Zylon TM织物的内部相对松弛或低张力可变形层被安装到风扇壳体外表面并且包围冲击区域。 可压缩(例如金属泡沫或蜂窝)层安装在可变形层的外表面上。 Teflon TM的摩擦减小层安装在可压缩层的外表面上,并且Kevlar TM或Zylon TM织物的外部较紧张的较高张力容纳层安装在摩擦减小层的外表面上 。 摩擦减小层通过减小可压缩层和容纳层之间的局部剪切应力来增强围绕可压缩层的圆周的冲击力的分布。
