20100061856 | STEAM TURBINE ROTATING BLADE FOR A LOW PRESSURE SECTION OF A STEAM TURBINE ENGINE - 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 skewed 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 comprises a first flat section, a second flat section, and a depression section located laterally between the first flat section and second flat section. The depression section is located below the first flat section at a first end where the first flat section and depression section are contiguous. The depression section rises above to the second flat section at a second end where the second flat section and depression section are contiguous. The second flat section is raised above the first flat section. The cover is positioned at an angle relative to the tip section, wherein the angle ranges from about 10 degrees to about 30 degrees. | 03-11-2010 |
