FIELD: machine building.
SUBSTANCE: invention relates to a turbomachine blade, method of its manufacturing, a turbomachine disk and a turbomachine equipped with a variety of blades. The method involves production of a solid fibre workpiece by 3D weaving. The fibre workpiece is shaped so that to produce a solid preform with the first part being a preform of the blade airfoil and root. There are two sides at the airfoil, each of them connects the entrance edge to the exit edge, the preform has also the second part present only on one of the blade airfoil sides and being a preform for at least one of the following elements: a root platform, an anti-inclination wall, spoilers of peripheral platform and ridges of peripheral platform. The preform is packed by mould to get a blade made from composite material with fibrous reinforcement consisting of the preform and packed by the mould and forming a solid unit with at least part of one of the following blade elements: the root platform, the anti-inclination wall, the spoilers of peripheral platform and ridges of peripheral platform present only on one side of the blade airfoil.
EFFECT: invention ensures improvement of physical-mechanical properties of a blade.
