COOLING PASSAGE EXIT OPENING CROSS-SECTIONAL AREA REDUCTION FOR TURBINE SYSTEM COMPONENT - A simplified explanation of the abstract
This abstract first appeared for US patent application 18377080 titled 'COOLING PASSAGE EXIT OPENING CROSS-SECTIONAL AREA REDUCTION FOR TURBINE SYSTEM COMPONENT
Simplified Explanation: The patent application describes a turbine system component with a cooling passage that has a hollow member reducing the cooling capabilities by creating a smaller exit opening.
- The component has a body with an exterior surface and a cooling passage.
- A hollow member is coupled in the cooling passage, defining a smaller exit opening at the exterior surface.
- The hollow member has a melt temperature higher than the turbine system's operating temperature.
- By reducing the exit opening's cross-sectional area, the cooling capabilities of the passage are decreased.
- A cooling profile can be generated to identify and modify cooling passages with excess cooling.
Key Features and Innovation:
- Cooling passage with a hollow member reducing cooling capabilities.
- Hollow member with a smaller exit opening than the original passage.
- Material of the hollow member has a higher melt temperature than the operating temperature.

Original Abstract Submitted
A turbine system component includes a body having an exterior surface, and a cooling passage defined in the body. The cooling passage has a first cross-sectional area in the body. The component also includes a hollow member defining a first exit opening at the exterior surface of the body and coupled in the cooling passage. The hollow member, at the first exit opening, has a second cross-sectional area that is less than the first cross-sectional area, creating an exit opening with a smaller dimension than the original cooling passage. The hollow member is made of a material having a melt temperature higher than an operating temperature of the turbine system. The hollow member(s) reduces the cooling capabilities of the cooling passage. A cooling profile of the component can be generated to identify those cooling passages having excess cooling so they can have their exit openings reduced in cross-sectional area.
