FIELD: process and equipment for casting monocrystalline working vanes of gas-turbine engines. SUBSTANCE: apparatus includes ceramic mold having upper head, working, starting-up and additional head cavities. Additional cavity is arranged outside mold over narrow portion of turbine vane in zone of molding vane fin. Lengthwise axes of working and starting- up cavities are inclined by angle equal to (5-20) degrees relative to vertical line. It allows to replenish liquid phase in zone of shroud flange of vane. Apparatus may include at least one additional ceramic mold. In such case upper head cavities are combined. EFFECT: less loss of yield due to increased density of casting structure. 2 cl, 1 dwg, 1 ex
