Title: Yugo Tokunaga: Innovator in Turbine Blade Technology
Introduction
Yugo Tokunaga is a prominent inventor based in Takasago, Japan. He has made significant contributions to the field of turbine blade technology, holding two patents that focus on evaluating the fatigue life of turbine blades. His work is essential for enhancing the reliability and performance of turbine systems.
Latest Patents
Tokunaga's latest patents include a turbine blade fatigue life evaluating method. This method quantitatively assesses the fatigue life of a turbine blade by determining its creep elongation strain in the longitudinal direction. If the strain is less than 0.5% of the initial length, the turbine blade is considered to be within its fatigue life. Conversely, if the strain is 0.5% or more, it is deemed to have exceeded its fatigue life. Additionally, he has developed a turbine blade creep elongation strain measuring apparatus, which consists of a first fixed end, a second fixed end, and a dial gauge. A dimension in the longitudinal direction is stamped on the surface of the turbine blade for accurate measurement.
