具有改进的密封的涡轮叶片和涡轮
摘要：
本发明涉及具有改进的密封的涡轮叶片和涡轮。本公开涉及具有燃气涡轮叶片(1)和转子隔热罩(7)的涡轮，转子隔热罩(7)用于使热的工作介质流过其的空间区域与涡轮的转子布置内部的空间区域分开。转子隔热罩(7)包括：平台，其形成轴向隔热罩区段(14)，并且布置成大致平行于转子(6)的表面；以及在轴向隔热罩区段(14)的上游端处的径向隔热罩区段(15)，其沿远离轴向隔热罩区段(14)的表面的方向朝热气延伸。另外，涡轮包括由平台(2)的下游端和/或叶片足部(4)的下游端、径向隔热罩区段(15)界定的叶片后部腔体(16)。本公开进一步涉及针对此类涡轮设计的燃气涡轮叶片(1)和转子隔热罩(7)。
摘要（英）：

The disclosure pertains to a turbine with a gas turbine blade (1) and a rotor heat shield (7) for separating a space region through which hot working medium flows from a space region inside a rotor arrangement of the turbine. The rotor heat shield (7) comprises a platform which forms an axial heat shield section (14) and which is arranged substantially parallel to the surface of a rotor (6) and a radial heat shield section (15) at the upstream end of the axial heat shield section (14), which is extending in a direction away from the surface of the axial heat shield section (14) towards the hot gas. Further the turbine comprises a blade rear cavity (16) which is delimited by the downstream end of the platform (2) and/or the downstream end of the blade foot (4), the radial heat shield section (15). The disclosure further refers to a gas turbine blade (1) and a rotor heat shield (7) designed for such a turbine.
