FIELD: process engineering.
SUBSTANCE: invention relates to production of turbomachine irregular shape blade from composite and to turbomachine with such blade. In compliance with this invention, fibrous integral blank is made by 3D weaving. Fibrous blank is shaped so that fibrous preform is produced that contains first part making the root preform and butt preform and at least one second part making the blade shroud. Preform is compacted by female die to produce preform of irregular including fibrous carcass made by preform and compacted by female die, said blade making an integral part with shroud. Said part is weaved so that it includes first part to make, after shaping, the fibrous preform first part and second part to make, after shaping, the fibrous preform second part.
EFFECT: higher mechanical properties of irregular shape blade.
