Leakage Prevention TRIZ Cases
- Turbomachinery Module Sectorized Sealing Ring Offset Foil
Offsetting foil sector edges blocks hot gases from casing rails, preventing thermal deformation and extending turbomachine service life.
- CMC Turbine Ring Assembly Mounting on Cross-Member
Direct CMC sector retention eliminates metal casings, reducing weight while managing thermal expansion differences.
- Variable Airfoil Sealed Flowpath for Gas Turbine Leakage Reduction
Segmented airfoil members pivot to adjust airflow direction while maintaining airtight radial seals, reducing leakage around variable stator vanes.
- Flexible Metallic Seal for Turbine Transition Duct Thermal Shifts
Flexible metallic seals accommodate thermal expansion at the offset transition duct interface, preventing gaps and leakage to maintain seal integrity.
- Steam Turbine Shell Support Thermal Control
Shell support structure with interior passageway for heating or cooling medium to match thermal growth rates.
