FIELD: aircraft compressors and turbines. ^ SUBSTANCE: proposed blade includes vane with leading and trailing edges and platform. Vanes and platform are made in form of separate interconnected monocrystals. Each monocrystal has different direction of crystallization relative to longitudinal axis of blade. Deviation from direction of crystallization of vane and/or platform and direction of maximum working tension stresses does not exceed 15 deg. ^ EFFECT: improved properties and quality; enhanced durability; facilitated procedure of repair and application of protective coats. ^ 3 cl, 3 dwg |
