1Productivity
If conventional airfoil profiles are used in compressor rotor blades, then the design is simpler and easier to manufacture, but compression efficiency and energy transfer are suboptimal
Solution Approach 1:
The patent applies parameter changes by precisely modifying the geometric parameters of the airfoil profile using specific Cartesian coordinate values. This optimization of shape parameters improves compression efficiency and energy transfer while maintaining manufacturability through defined coordinate specifications.
2Power
If optimized airfoil profiles with specific coordinate values are implemented, then energy transfer and pressure increase are improved, but manufacturing precision requirements increase
Solution Approach 1:
The patent specifies precise parameter changes through defined Cartesian coordinate values (X, Y, Z) that optimize energy transfer and power characteristics. The coordinates are provided with specific precision levels to balance manufacturing feasibility with performance optimization.
3Productivity
If stage-specific airfoil profiles are used, then operational performance at each compressor stage is optimized, but the overall system complexity increases
Solution Approach 1:
The patent applies local quality by providing different optimized airfoil profiles tailored to specific compressor stages (e.g., third stage rotor blade). Each stage receives a customized profile with specific coordinate values optimized for its local operating conditions, improving overall system performance despite increased complexity.
