Engineering Contradiction Analysis
1Productivity
If conventional airfoil profiles are used in compressor stages, then the compressor can be manufactured with standard designs, but the compression efficiency and energy transfer are reduced
Solution Approach 1:
The patent applies parameter changes by precisely modifying the airfoil profile geometry through specific Cartesian coordinate values. The suction side and pressure side coordinates define an optimized airfoil shape that changes the flow characteristics, enabling better velocity matching and turning speeds in compressor stages, thereby improving compression efficiency and reducing energy consumption.
2Productivity
If optimized airfoil profiles with specific coordinate values are implemented, then velocity matching and turning speeds are improved, but the manufacturing complexity increases
Solution Approach 1:
The optimized airfoil profile is segmented into discrete Cartesian coordinate points that define the suction side and pressure side geometry. This segmentation allows the complex curved profile to be manufactured using precision machining or additive manufacturing by following the specified coordinate values, making the complex shape manufacturable through digital fabrication methods.
