ABSTRACT:
A method for providing a scalable two tang side entry turbine blade root geometry which significantly reduces stress concentration due to centrifugal and bending load on the blade root by equalizing the stresses at all points of stress concentration utilizing a scalable model in which all of the dimensions can be multiplied by a constant to produce a range of different sized blade roots.
