FIELD: engine devices and pumps.
SUBSTANCE: three-layer blanks of skins and/or aggregate are used, wherein the outer layers of blanks are made of titanium alloy with different grain sizes. Applying an anti-adhesive coating to the surface of the sections of blanks of skins and/or aggregate blank that are not subjected to bonding during diffusion welding, assembling the skin and aggregate blank in a package, sealing the package along the edges, welding the gas injection tube to the package, evacuating package cavity when it is heated, heating the package, diffusion welding of blanks, rupture of adhesive bonds between blanks, superplastic forming before obtaining a hollow blade feather.
EFFECT: increasing the quality of aggregate connection with skins.
