    摘要: In summary the invention relates to a turbine blade (10) with an airfoil comprising next to each other a main body (26) in a tip region (28), said tip region (28) ends in one or more free endings squealer tips (34), wherein the tip region (28) comprises a transition zone (30) with varying material composition and a end zone (32) having a constant material composition, wherein the transition zone is located between the end zone and the main body (26), the material composition in the transition zone (30) vary in a direction to the end zone (32) by continuously changing its local oxidation resistant properties. With such a turbine blade it is possible to have a longer operation time with reduced tip clearances leading to longer lasting high efficient operation of a turbine.

    摘要: An anti-icing exhaust system for an inlet of a gas turbine engine is provided. The system includes a first housing portion that at least partially defines a chamber to receive an anti-icing fluid and includes a projection. A second housing portion includes a leading edge. The system includes a support structure that couples the first housing portion to the second housing portion such that the projection of the first housing portion is spaced apart from the leading edge of the second housing portion to define a gap. The gap is in fluid communication with a manifold. The support structure defines at least one flow passage in fluid communication with the chamber and the manifold to exhaust the fluid. The system includes an insulation strip having a first end received in the gap and coupled to the leading edge; and a second end coupled to the second housing portion.
