<p><P>PROBLEM TO BE SOLVED: To provide a turbine end wall structure increasing advantages of cooling of a cooling medium flow by machining a passage, or molding the passage together with an aerofoil section. <P>SOLUTION: The aerofoil section (30) includes a vacuum surface (33) and a positive pressure surface (34) which are opposed to each other, extend between radial ends (31), and are joined to each other at a leading edge (35) and a trailing edge (36) to define an aerofoil inside (37). The positive pressure surface (34) is configured to further define the passage (50) feeding a cooling medium from the aerofoil inside (37) by the positive pressure surface (34). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
