A lightweight steam turbine blade includes a metallic airfoil portion with at least one surface recess containing a void volume having adjacent first and second regions. Filler material is placed in and bonded to the surface recess and generally completely fills the void volume. The filler material in the first region has a higher average modulus of elasticity than that of the filler material in the second region.

Steam turbine blade having areas of different densities

A lightweight, impact-resistant gas turbine blade, such as an aircraft engine fan blade, has an airfoil portion. The airfoil portion includes a metallic section consisting essentially of metal and at least one 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. Preferably, the metallic section and the at-least-one panel section only together define a generally airfoil shape.
