During operation, the blade is exposed to erosion-prone particles, with the greatest impact in the zone of inlet 1 and outlet 2 edges, as well as the trough. Pads 3, 4 jMenbUiairaosocon the effect of the particles due to the quenching of their kinetic layers due to the elastic properties of the material filling the cells of the grid 5, and also protect the edges 1, 2 from erosion. Coating 9 also fuses the reduction of erosion of particles by their kinetic energy. Grid 5, fixed with ends 7 in the body of the blade, reinforcement pad 3, 4, can increase their Yarostnost, as well as the strength of the joint of the latter with the body of the blade. Reducing the effect of stress concentration in the blade from the ends 7 of the grid 5 is achieved by placing them at an angle fi to the edges and securing them to different from them. distance x F o rm a lu inventions. . Linztka turbomaivip of kompozpshyuinogo materigsha comprising zakregshennye the input and vyho / dpoy edges protective lining in the form of wire mesh, on t l ichayuscha the fact that, in order povysheshsh reliability of the cell grid filled eroznonnostoykim zlastishym pictures, its ends are bent to the profile of the blade, and the section of the trough of the latter between the plates has a coating of elastic material. 2 A blade according to claim 1, in connection with the fact that, in order to reduce the co-fracture of the stresses, the ends of each lining are angled to the edge and fixed at a distance from it.
