![]() ![]() The turbine blade as defined in claim 1, wherein the ribs include a first rib disposed toward the pressure side and a second rib disposed toward the suction side, the first rib connects the downstream fin at a point vertically aligned with suction side of a cross-section of the airfoil portion taken at a connection with the shroud.Ĩ. The turbine blade as defined in claim 1, wherein the ribs include a first rib disposed toward the pressure side and a second rib disposed toward the suction side, the first rib connects the upstream fin at a point disposed between 25% and 60% of a first distance from a first point, the first point being a point on the upstream fin vertically aligned with the pressure side of a cross-section of the airfoil portion taken at a connection with the shroud, the first distance being a distance between the first point and a second point, the second point being the extremity of the upstream fin on the pressure side.ħ. The turbine blade as defined in claim 1, wherein the angle formed by the ribs is comprised between 20 and 30 degrees.Ħ. The turbine blade as defined in claim 1, wherein the upstream and downstream fins are inclined relative to a normal to the outer face.ĥ. The turbine blade as defined in claim 2, wherein each of the two outer ribs partially define a contact face on each of the pressure side and suction side.Ĥ. The turbine blade as defined in claim 1, wherein the ribs are inner ribs and further comprising two outer ribs extending outwardly from the outer face, the outer ribs extending from and to the opposed ends of the fins, the inner ribs being disposed between the outer ribs.ģ. A turbine blade for a gas turbine engine, the blade comprising: a platform a blade root extending radially inwardly from the platform an airfoil portion extending radially outwardly from the platform, the airfoil portion defining a pressure side and a suction side of the turbine blade and a shroud provided at a tip of the airfoil portion opposite to the blade root, the shroud including: a body having a radially outer face opposite to the airfoil portion upstream and downstream fins extending outwardly from the outer face, the fins being generally parallel to each other, each of the fins having an end disposed toward the pressure side and another end disposed toward the suction side two ribs extending outwardly from the outer face, the ribs extending from and connecting the upstream fin to the downstream fin at locations other than the ends of the upstream and downstream fins, the ribs converging toward the downstream fin at an angle of between about 10 and about 45 degrees without intersecting each other.Ģ.
