FIELD: engines and pumps.
SUBSTANCE: gas turbine blade is provided with an attachment part and roof part to which blade feather with the top of blade feather, which includes two opposite thin-walled bent elements, is attached. Thin-walled bent elements as blade feather wall located on suction side and as blade feather wall located on pressure side are attached to each other. Both thin-walled bent elements in the area of blade feather top are protected against divergence by means of body closure formed by means of the attaching device with the help of hooks, which, when being located between both thin-walled bent elements, comprises the engagement between them. Each thin-walled bent element includes a hook; at that, those hooks being made as the attaching device by means of hooks to each other are engaged to each other. The other invention of the group refers to gas turbine including the above blade.
EFFECT: invention allows increasing turbine reliability and decreasing flow losses owing to preventing divergence of thin-walled bent elements.
