FIELD: machine building.
SUBSTANCE: turbine component has a blade, a carrying element, and four boundary surfaces between the blade and the carrying element. Each of the boundary surfaces is sealed using plate seals. The first boundary surface is located at the side of the face edge radially to the outer blade platform, the second boundary surface is located at the side of the face edge radially to the inner blade platform, the third boundary surface is located at the side of the rear edge radially to the outer blade platform, and the forth boundary surface is located at the side of the rear edge radially to the internal blade platform. The plate seals are connected with the blade and/or with the carrying element ensuring the possibility of movement between the blade and the carrying element. Another invention of the group relates to the method of sealing against leak between the blade and the carrying element, when the said boundary surfaces are sealed using the plate seals.
EFFECT: possibility of movement between the blade and the carrying element upon keeping sealing characteristics.
