Steam turbine rotating blade for a low pressure section of a steam turbine engine

A low pressure turbine section of a steam turbine, comprising:

• a plurality of latter stage steam turbine blades arranged about a turbine rotor, wherein each of the plurality of latter stage steam turbine blades comprises:
• an airfoil portion having a length of about 20.4 inches (51.82 centimeters) or greater;
• a root section attached to one end of the airfoil portion;
• a dovetail section projecting from the root section, wherein the dovetail section comprises a straight axial entry dovetail;
• a tip section attached to the airfoil portion at an end opposite from the root section;
• and
• a cover integrally formed as part of the tip section, wherein 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 being positioned at an angle relative to the tip section, the angle ranging from about 15 degrees to about 35 degrees.
