Abstract RU 2515861 C2

FIELD: process engineering.

SUBSTANCE: invention relates to production of gas turbine blades. In compliance with this method, visibility of cut ends of pre-form threads is improved to make curved lines of substrate threads visible. Configuration of said curved lines is compared with reference configuration for satisfactory forming of said pre-form.

EFFECT: higher operating performances of said vanes.
