Latest Patents
Yamashita's latest patents include innovative designs for turbine components. One of his notable inventions is a turbine bucket designed for steam turbines. This turbine bucket features an exhaust area exceeding 9.6 and 13.8 for low-pressure final stage buckets, suitable for rated speeds of 3600 rpm and 300 rpm machines, respectively. The bucket is constructed from martensite steel, ensuring durability and performance. Additionally, the blade portion of the turbine bucket is intricately designed with a suction surface and a pressure surface, each formed at the turbine blade root, consisting of three areas: a steam inlet side area with curvature, a steam outlet side area with curvature, and an approximately straightly formed area located between the two.
Another significant patent is for a turbine moving blade. This blade has a portion extending from the basal portion to the tip, with the blade root portion formed at the basal portion and engaged with a corresponding disk groove of a turbine rotor. The integral cover at the tip of the blade portion is designed to include at least a pair of pressure and suction sloped surfaces. These surfaces are inclined relative to the direction of the rotational axis of the turbine, which helps to restrain the elastic restoring force of the moving blade when it is torsionally deformed during installation.
