FIELD: manufacturing technology.
SUBSTANCE: disclosed is turbine nozzle vane (180) containing aerodynamic part, having aerodynamic shape. Aerodynamic part has optimum profile, substantially in compliance with values of X, Y and Z of rectangular coordinate system given in Table 1. Said values X, Y and Z are non-dimensional values with values from 0 % to 100 %, convertible into dimensional distances in inches (cm) by multiplying these values X, Y and Z to height of blade aerodynamic part in inches (cm). X and Y represent distances in inches (cm), which, being connected by smooth continuous arcs, setting blade aerodynamic part profile cross-sections at every distance Z. Blade aerodynamic part profile cross-sections at distances Z are smoothly connected to each other with formation of complete aerodynamic shape.
EFFECT: enabling optimum conditions and technical characteristics of aerodynamic efficiency and standardized aerodynamic and mechanical loads of blade.
