内部冷却構造。In a two-shaft gas turbine engine that has a partition wall on the inner side of the gas passage that communicates the compressor turbine and the output turbine, a center hole is provided that communicates with the gas generator main shaft and the center bolt on the compressor turbine side. The central hole communicates with the pressure chamber behind the compressor impeller, and the partition wall is provided with a plurality of through holes, and the total area of these through holes is the sum of the annular gaps in the axial direction of the compressor turbine disk and the output turbine disk. An internal cooling structure for a gas turbine engine characterized by having a larger area.
