Axial-flow compressor

Abstract

Abstract PURPOSE:To prevent reduction of the surface pressure on a disk in revolution by forming in a disk during rotor revolution, ventilation holes for ventilating high-temperature gas and allowing a large thermal expansion to be generated on the disk. CONSTITUTION:A portion of the pressurized high-temperature gas goes to the hollow part 4b, passing through the gap 29 between a diaphragm 21 and an end piece 4 and a through-hole 11, and then a portion of said gas go to the hollow part 3b, passing through the ventilation holes 7 and 8 inside a disk 1, and the rest go to the hollow part 3b, passing through a slit 12, ventilation hole 9, and a slit 33, and then all the gas are joined and introduced outside, passing through ventilation holes 14, 16, 18 and 20, as shown with an arrow of solid line. As the disk 1 is thereby heated by the high-temperature gas, thermal expansion is generated, and reduction of the surface pressure on the disk in revolution can be prevented.
