ABSTRACT:
A turbine blade has a hole through the blade stalk and a controlled area in the stalk cross section on each side of the hole to assure that the blade will separate at the stalk upon overspeed of the turbine wheel. The hole is drilled and reamed and the hole surface is finally machined by chemical milling to eliminate stress risers while maintaining a controlled cross-sectional area to ensure that with selected wheel and blade materials, the blades will separate and reduce the speed of the turbine wheel.
