Turbine Disk Support Plate Segmented Fixing Blocks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing turbine apparatuses face challenges in easily integrating a support plate onto a turbine disk, which complicates the assembly and stability of blades.
Innovation Solution
A turbine apparatus design featuring a turbine disk with protrusions and latching portions, supported by first and second fixing blocks, where the second fixing block's space width is narrower than the first, allowing for secure engagement and easy installation of a support plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a support plate is provided on a turbine disk using conventional methods, then the blades can be supported, but the assembly process becomes complicated and difficult to install
Solution Approach 1:
The support plate is divided into multiple segments corresponding to different radial positions. Each segment has protrusions that engage with recesses in the turbine disk, allowing the support plate to be assembled in a modular fashion rather than as a single complex piece, thereby simplifying the installation process
Solution Approach 2:
Protrusions and recesses serve as intermediary elements that facilitate the connection between the support plate segments and the turbine disk. These intermediate features enable easy alignment and secure attachment without requiring complex fastening mechanisms
2Stability of the object's composition
If the support plate is securely fixed to prevent movement and rotation, then blade stability is improved, but the fixing mechanism becomes more complex
Solution Approach 1:
The protrusions on the support plate segments are designed with asymmetric shapes that correspond to asymmetric recesses in the turbine disk. This asymmetric geometry provides inherent anti-rotation capability, as the protrusions can only engage with their matching recesses in a specific orientation, thereby preventing rotation without requiring additional locking mechanisms
Solution Approach 2:
Instead of using conventional fastening methods that require bolts or clips to prevent rotation, the design inverts the approach by using the protrusion-recess geometry itself to provide both the connection and the anti-rotation function. The shape of the protrusions is specifically designed to physically block rotation in the opposite direction
