用于涡轮叶片平台-翼型件接头的冷却
摘要：
本发明涉及用于燃气涡轮的涡轮叶片(10)，其包括平台部件(12)和翼型件部件(14)。平台部件(12)包括平台表面(16)，其布置成附连到翼型件部件(14)的对应的翼型件表面(18)上。涡轮叶片(10)进一步包括用于冷却平台和翼型件表面的冷却管(20)，冷却管(20)包括在平台表面(16)中的至少一个腔体(22)和在对应的翼型件表面(18)中的至少一个腔体(22)，并且平台和翼型件表面腔体对齐，使得当平台表面(16)和翼型件表面(18)接触时，冷却管(20)保持畅通。这提供冷却平台和翼型件表面两者的可靠冷却手段。
摘要（英）：

The invention concerns a turbine blade 10 for a gas turbine comprising a platform part 12 and an aerofoil part 14. The platform part 12 comprises a platform surface 16 arranged to be attached to a corresponding aerofoil surface 18 of the aerofoil part 14. The turbine blade 10 further comprises a cooling duct 20 for cooling the platform and aerofoil surfaces, the cooling duct 20 comprising at least one cavity 22 in the platform surface 16 and at least one cavity 22 in the corresponding aerofoil surface 18, and the platform and aerofoil surface cavities are aligned such that when the platform surface 16 and the aerofoil surface 18 are touching, the cooling duct 20 remains open. This provides a reliable cooling means that cools both the platform and aerofoil surfaces.
