Patent number: 11203941Abstract: A stationary blade includes a main unit having a hollow blade structure formed from a metal plate by plastic forming. The stationary blade includes a blade tail section. In a blade tail upper portion, the metal plate has a concave-shaped recess and a rib formed on an inner surface side thereof, and the metal plate further has slits formed by slitting on a blade pressure side thereof, so that droplets affixed on a blade surface can be guided into an inside of the hollow blade when the blade tail section is joined to the hollow blade main unit. The recess in the metal plate is covered so as to be lidded by a suction-side protrusion of a suction-side metal plate from a blade suction side to thereby form a hollow blade tail section. The metal plates are welded together to the main unit.Type: GrantFiled: September 10, 2020Date of Patent: December 21, 2021Assignee: Mitsubishi Power, Ltd.Inventors: Susumu Nakano, Koji Ishibashi, Shunsuke Mizumi, Masaki Matsuda, Takeshi Kudo
