Abstract

The invention proposes a technique to control leakage to the main flow path in compressor rotor front stages. The technique includes a wire seal in compressor rotor front stages. As shown in figure 1, the wire seal is provided between T34 and R4. Another wire seal is provided between T23 and R3. Such wire seals reduces rotor critical outflow leakages of R2 and R3.
