TURBINE BLADE AND ITS USE IN A GAS TURBINE SYSTEM

摘要

A turbine blade (1) has a wall structure (2) around which a hot gas (18) can flow. The wall structure (2) has a cooling area (5) through which a cooling fluid (6) flows between an outer wall (3) and an inner wall (4). Each cooling area (5) has heat transfer elements (7) around which the cooling fluid (6) can flow. The heat transfer elements (7) are successively arranged in a main flow direction (12) and are thermoconductively connected to the outer wall (3).
