Aerodynamic Vein Modification Patch for Turbomachine Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing design and production of aerodynamic veins in turbomachines are complex, expensive, and time-consuming, requiring multiple iterations for optimization, and existing methods for modifying these veins are costly and involve lengthy manufacturing processes.
Innovation Solution
A modification part, or 'patch,' is designed to be attached to the aerodynamic vein, allowing for a quick and inexpensive modification of the vein's profile without the need for new bulky parts or disassembly of the turbomachine, using a first face that matches the initial profile and a second face that defines a new modified profile, which can be made from materials like stereolithographic resin and fixed using adhesives or mechanical fasteners.

Engineering Contradiction Analysis
1Reliability
If aerodynamic veins are machined directly on turbomachine parts, then the aerodynamic performance is optimized, but the manufacturing complexity and cost increase significantly
Solution Approach 1:
The aerodynamic vein modification is divided into two segments: the original vein structure and the separately manufactured modification part. This allows the modification part to be optimized independently for aerodynamic performance while the original structure remains unchanged, reducing overall manufacturing complexity.
Solution Approach 2:
Instead of machining the complete aerodynamic vein directly on the turbomachine part, a modification part is created that copies or replicates the desired aerodynamic profile. This modification part can be manufactured using simpler processes and then attached to the original structure.
2Reliability
If aerodynamic veins are modified through multiple test iterations, then the optimal design is achieved, but the development time and cost increase
Solution Approach 1:
The modification part is designed to be dynamically replaceable on the turbomachine. This enables rapid iteration of different aerodynamic profiles by simply replacing the modification part rather than redesigning and remanufacturing entire components, significantly reducing development time for optimization.
Solution Approach 2:
The modification part allows for easy variation of aerodynamic parameters (such as profile shape, angle, curvature) without changing the base turbomachine structure. This facilitates rapid testing of different parameter combinations to achieve optimal aerodynamic performance.
3Shape
If complete aerodynamic veins are replaced to modify the profile, then the desired profile change is achieved, but the manufacturing cost and time increase
Solution Approach 1:
The aerodynamic vein system is segmented into the original vein and a separate modification part. Only the modification part needs to be manufactured with the new profile, while the original vein structure can be reused, significantly reducing manufacturing effort and cost.
Solution Approach 2:
The modification part is designed to fit onto or integrate with the existing aerodynamic vein structure, similar to a nested doll configuration. This allows the new profile to be achieved by adding a layer rather than replacing the entire structure.
