FIELD: engines and pumps.
SUBSTANCE: device for attachment of guide vanes of turbine, which is fixed on support that in its turn is installed on stabilising part, contains slot connection devices for connection to slot of the support edge with stabilising edge of stabilising part, retention part for retention in slot of support edge and stabilising edge and retention devices for prevention of relative rotation of support edge and stabilising edge. Retention devices include at least one groove having semispherical shape in its section and made on plane of support edge, and at least one groove having semispherical shape in its section and made on plane of stabilising edge. Grooves are arranged one opposite another and form retention hole at installation of both edges into the slot. The other invention of the group refers to turbine containing the above device for attachment of guide vanes. One more invention refers to aircraft engine containing the above turbine and/or the above device for attachment of guide vanes.
EFFECT: inventions allows simplifying and reducing the weight of the attachment device of turbine guide vanes.
