Steam turbine rotating blade for a low pressure section of a steam turbine engine |
摘要 |
A steam turbine rotating blade for a low pressure section of a steam turbine engine is disclosed. The steam turbine rotating blade includes an airfoil portion. A root section is attached to one end of the airfoil portion. A dovetail section projects from the root section, wherein the dovetail section includes a straight axial entry dovetail. A tip section is attached to the airfoil portion at an end opposite from the root section. A cover is integrally formed as part of the tip section. The cover has a first portion that overhangs a pressure side of the airfoil portion and a second portion that overhangs a suction side of the airfoil portion. The cover is positioned at an angle relative to the tip section, wherein the angle ranges from about 15 degrees to about 35 degrees.
