Latest Patents

Takeshi Nakamura's latest patents showcase his expertise in developing sealing solutions for gas turbines. His exemplary work includes:

1. **Seal structure between gas turbine discs**: This invention addresses the need for improved sealing performance between the rotor's interior and the gas path of a steam cooling type gas turbine. The unique design incorporates a groove along the circumferential direction of disk lands, allowing for an annular sealing member that ensures effective inter-disk sealing. This prevents leakage of cooling steam and mitigates self-induced vibrations, ultimately enhancing the overall efficiency and reliability of gas turbines.

2. **Gas turbine spindle bolt seal device**: This patent focuses on a sealing device that utilizes steam to cool high-temperature sections of the gas turbine while recovering the steam. It effectively seals the spindle bolt portion of the turbine disc, preventing steam leakage. By employing a seal piece with a smaller coefficient of linear expansion compared to the spindle bolt, and introducing high-pressure steam into the sealing mechanism, it ensures a tight seal is maintained during operation.
