Title:
GAS TURBINE STRUCTURE
Document Type and Number:
Japanese Patent JPS60259705
Kind Code:
A
Abstract:
PURPOSE:To restrain a disk and moving blade from overheat by forming a plurality of rings of moving blade rows on one surface of a turbine disk and forming a flow path through which cooling medium passes in a space in which fan blades radially planted in the opposite surface are rotated. CONSTITUTION:A plurality of moving blades 7 are planted concentrically with a rotor shaft 3 in one surface of a turbine disk 6 secured fixedly to the rotor shaft 3 to form a plurality of rings of the annular moving blade rows. On the other hand, a plurality of fan blades 9 are planted in the opposite surface of the turbine disk 6 to form a flow path 15 through which cooling medium passes in a space in which the fan blades 9 rotate. Thus, as the turbine disk 6 is rotated, the atmosphere, i.e. cooling medium is introduced into said flow path 15 from an intake port 16 so that the turbine disk 6 and the moving blades 7 can be prevented from overheat.
