FIELD: turbines or turbomachines.
SUBSTANCE: composite blade of compressor of axial turbomachine includes blade passing in radial direction in flow of turbomachine and including front and rear edges, and also main part between them, and reinforcing element with located upstream part, having constant thickness and C-shaped radial section and forming front blade edge. Reinforcing element additionally comprises reinforcing sheet, having constant thickness, where it is covered with main part, and passing from front edge to rear edge. Reinforcing sheet is located in thickness of main part for passage through it and includes edge of reduced thickness forming rear edge of blade. Another invention of the group relates to a turbomachine comprising said blade.
EFFECT: group of inventions improves stiffness of turbomachine blade.
