<p>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.</p> |
