Abstract
A steam turbine blade, such as those used in an electric power generation steam turbine, has an airfoil portion. The airfoil portion includes a metallic section consisting essentially of metal and at least one (lightweight) panel section not consisting essentially of metal. The metallic section extends from generally the blade root to generally the blade tip. Each panel section is an elastomeric section. The metallic section and the at-least-one panel section only together define a generally airfoil shape.
