IPC: F01D5/08
Filed: 1993-07-13
Abstract: PURPOSE:To prevent a disc from being deformed due to a temperature difference, in a turbine in which coolant having passed through a cooling passage in a rotor blade is retrieved through the side wall of the disc, by providing a bypass passage bypassing the cooling passage in the rotor blade, in the vicinity of the outer periphery of the disc. CONSTITUTION:During rotation of rotor blades 2, compressed air from a compressor is led to one of the surfaces of a disc 11 through a passage in a rotary shaft 24, being led to the radially outside of the disc which is therefore cooled under forced convection, and is then led through a cooling passage in each of the rotor blades 2. The compressed air having cooled the rotor blade 2, is led toward the radially inside of the disc 11 along the other one of the surfaces of the disc 11, and is retrieved. In this arrangement, a bypass passage 9 communicating between both side wall surfaces 11a, 11b of the disc is formed in the disc 11 in the vicinity of the outer periphery of the disc 11. Accordingly, the coolant which has cooled the rotor blade 2 so as to have a high temperature is diluted with coolant having passed through the bypass passage 9 so as to lower the temperature thereof, thereby it is possible to prevent the disc from being deformed due to a difference in temperature between both side wall surfaces of the disc.
