Abstract
A turbine rotor blade made from a spar and a shell each having an airfoil cross sectional shape and each formed from a high temperature exotic material and formed by a wire EDM process to form a thin wall shell from Molybdenum and the spar from Waspalloy or IN100 in order to form a turbine blade that requires very low amounts of cooling air while allowing for high temperature use above what nickel super alloys can be exposed to. The spar and shell are secured to the platform by a bolt passing through the widest section of the hollow spar and connected at one end to a tip cap and to the other end to the platform and root piece of the blade.
