1st step high pressure turbine bucket wing shape section

摘要

The 1st step bucket (10), X where it states in chart 1, it possesses the wing shape section contour which you follow the Descartes coordinate value of Y and Z substantially, in said chart 1, Z, is vertical vis-a-vis the radius from the turbine centerline and is vertical direction distance from the plane surface which includes X and Y value, as for the said Z value, it is the coordinate which decides the wing shape section contour which X in the aerodynamics section of the radial most inside of the wing shape section, starts from zero inside Y plane surface, in addition X and Y, in each distance Z. X, as for Y and Z value, in order to obtain the wing shape section section for the bucket which it is expanded or is reduced, or, it is possible to be expanded to reduced as an identical constant or a function of numerical value.
