TURBINE NOZZLE ASSEMBLY WITH STRESS RELIEF STRUCTURE FOR MOUNTING RAIL - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240035388 titled 'TURBINE NOZZLE ASSEMBLY WITH STRESS RELIEF STRUCTURE FOR MOUNTING RAIL
Simplified Explanation
The abstract describes a turbine nozzle assembly that includes an airfoil and an outer endwall. A mounting rail is coupled to the outer endwall and extends radially outward and circumferentially along the endwall. The mounting rail has a stress relief structure, which includes an end opening, a slot, and an oblong opening. The oblong opening is asymmetrically arranged relative to the slot to relieve stress in the mounting rail.
- The turbine nozzle assembly includes an airfoil and an outer endwall.
- A mounting rail is coupled to the outer endwall and extends radially outward and circumferentially along the endwall.
- The mounting rail has a stress relief structure.
- The stress relief structure includes an end opening defined in the outer surface of the mounting rail.
- The stress relief structure also includes a slot defined through the thickness of the mounting rail and coupled to the end opening.
- Additionally, the stress relief structure includes an oblong opening defined through the thickness of the mounting rail and coupled to the radial inner end of the slot.
- The oblong opening is arranged asymmetrically in a circumferential direction relative to the slot to relieve stress in the mounting rail.
Potential Applications:
- Gas turbine engines
- Power generation systems
- Aerospace industry
Problems Solved:
- Reduces stress in the mounting rail of a turbine nozzle assembly
- Prevents potential damage or failure due to excessive stress
Benefits:
- Improved durability and reliability of turbine nozzle assemblies
- Increased lifespan of turbine components
- Enhanced performance and efficiency of gas turbine engines
Original Abstract Submitted
a turbine nozzle assembly includes at least one airfoil and an outer endwall coupled to a radial outer end of the at least one airfoil. a mounting rail is coupled to the outer endwall and extends at least partially radially outward from the outer endwall and at least partially circumferentially along the outer endwall. a stress relief structure is defined in the mounting rail. the stress relief structure includes an end opening defined in a radial outer surface of the mounting rail, a slot defined through the rail thickness of the mounting rail and coupled to the end opening, and an oblong opening defined through the rail thickness of the mounting rail and coupled to a radial inner end of the slot. the oblong opening is arranged asymmetrically in a circumferential direction relative to the slot to relieve stress where prevalent in the mounting rail.
