Abstract:
A method of manufacturing a turbine blade includes providing a core element having a base portion, a tip portion, and an intermediate portion extending between the base portion and the tip portion. The intermediate portion has a non-uniform cross-section and is a high-strength fiber material. The method also includes surrounding the core element with a shell, the volume between the core element and the shell forming a void.
