摘要： A gas turbine unit comprising:
- a combustor having a liner (4);
- a turbine, arranged downstream of the liner (4) along a main flow gas direction (M) and including a plurality of first stage vanes (28);
- a rotor cover support (6), located inwardly of the vanes (28) ;
- a sealing arrangement at the combustor to turbine interface (1) ;
wherein
the sealing arrangement comprises a first dogbone seal (3) extending between the rotor cover support (6) and an inner downstream end of the liner (4) or between the rotor cover support (6) and a bulkhead (5) located at the inner downstream end of the liner (4).摘要翻译： 一种燃气轮机单元，包括： - 具有衬套（4）的燃烧器; - 涡轮机，其沿着主流动气体方向（M）布置在衬套（4）的下游并且包括多个第一级叶片（28）; - 位于叶片（28）内部的转子盖支撑件（6）; - 燃烧室到涡轮机接口（1）处的密封装置; 其中所述密封装置包括在所述转子罩支撑件（6）与所述衬里（4）的内部下游端之间或者在所述转子罩支撑件（6）与位于所述转子罩支撑件（6）上的隔板（5）之间延伸的第一狗骨形密封件 内衬（4）的下游内端。
