  • Compressor to minimize vane tip clearance and gas turbine including the same
    Patent number: 11753954
    Abstract: Disclosed are a compressor, which is a cantilever type that is easy to manufacture and assemble, and is capable of minimizing the vane tip clearance as the elastic member absorbs the impact and is compressed when the vane collides with the shroud segment due to expansion of the vane, and a gas turbine including the same.
    Type: Grant
    Filed: January 31, 2023
    Date of Patent: September 12, 2023
    Assignee: DOOSAN ENERBILITY CO., LTD.
    Inventors: Oleksiy Korepin, Ievdoshyn Andrii, Dong Woo Ham

  • Compressor rotor disk for gas turbine
    Patent number: 11371527
    Abstract: A compressor rotor disk for a gas turbine includes a circumferential surface; and a plurality of dovetail slots formed along the circumferential surface, each dovetail slot comprising a cutout portion formed by removing a portion of a radially outer convex surface of the dovetail slot. The compressor rotor disk can reduce stresses generated in the compressor rotor disk by centrifugal force, by reducing the centrifugal force of the compressor rotor disk through the formation of the cutout portion at the radially outer portion of the compressor rotor disk, thereby enhancing the durability and reliability of the compressor rotor disk.
