FIELD: machine building.SUBSTANCE: group of inventions relates to the composite centrifugal impellers for the turbine machines. The centrifugal impeller for the turbine machine contains aerodynamic blades, each blade has internal walls connected with fabric element. First fabric elements are made with possibility of enclosing of each of specified aerodynamic blades. The second fabric element is made with possibility of enclosing one-by-one of top wall of the blade and bottom wall of the adjacent blade passing between them along the appropriate blade. Turbine machine is also described, it contains specified centrifugal impeller.EFFECT: group of inventions creates simple, quick and cheap die mould for the centrifugal impeller manufacturing.8 cl, 24 dwg |
