FIELD: manufacture of cast members of gas turbine engines.
SUBSTANCE: in first variant apparatus includes shaped sheet of refractory metal having several means for creating passages for film cooling. Such means are realized by bending sheet of refractory metallic material. In second variant apparatus includes metallic wall with aerodynamic profile and adjacent to said wall casting core of refractory metal. Contour of core corresponds to that of metallic wall.
EFFECT: possibility for casting different members of gas turbine engine.
