Abstract

PURPOSE: To reduce the loss of mismatching for a flow of gas in a built-up nozzle, by arranging an inflow angle at the central part of its strut in parallel to the rotary shaft core of a moving blade and titlting chip and base parts of the strut for the shaft core.
CONSTITUTION: A turbine stage is constituted by nozzles 3 and moving blades 4, and a strut 1 is provided as the reinforcement for a separator plate 2. Cross sections 1b of a base part B and chip part C in the strut 1 are titled for a axial core of the moving blade 4. While a mean part M is arranged in parallel to the axial core. Interim parts between the base part B and the mean part M and the mean part M and the chip part C are smoothly twisted. In this way, at portions of the base part B and the chip part C gas smoothly flows to decrease a loss of incidence and reduce an internal loss of the turbine. In consequence, a stage performance of the turbine can be improved.
