Abstract
PURPOSE:To enhance durability eliminating the necessity for providing an air passage in the center part of a turbine disk by providing the air passage in the peripheral side of an intermediate rotary shaft between a compressor rotor and the turbine disk and the second air passage, formed radially communicating with the former described air passage, in the turbine disk. CONSTITUTION:In the case of a gas turbine in which a compressor rotor 2b is connected through an intermediate rotary shaft 11 to the first stage turbine disk 32, many circular holes, which extend in the axial direction forming a cooling seal air flow path 15, are provided along the peripheral direction in a side wall part of the intermediate rotary shaft 11. While a cooling air passage 16a, for cooling an end surface of the disk 12, is provided in the intermediate rotary shaft 11 in its connection part to the above described disk 12. Further providing a rotor disk cover 17, integrally formed with the intermediate rotary shaft 11, in the outside of the connection part, a space part 19 is partitioned between the intermediate rotary shaft 11 and the disk 3 2, and the above described cooling air passage 16a and a cooling air passage 16b, cooling a turbine moving blade 9a, are opened to this space part 19.
