Customer Challenges
- A major aero-engine OEM wanted to redesign bearing housing due to its high cost and complex design
- The existing design consisted of 48 welded cast vanes which needed a very complex assembly process
Scope
- Redesign of aero engine bearing housing to reduce manufacturing cost
Solution
- New design proposed with a single piece casting and new assembly parts
- Proposed design checked for structural integrity and compatibility with the design standards of OEM
Benefits
- All redesign budgetary requirements met
- Manufacturing cost reduced because of casting
- Considerable reduction in weight
- Improved fuel consumption due to reduced aerodynamic wind steps in annulus
Results
- On-time delivery of design, 3D models, stress reports and manufacturing drawings
- 50% reduction of manufacturing cost
- 23% reduction of component weight
Features
- Complete design solution reports including stress analysis, life and engineering drawings
- Design complexity reduced from 48 welded vanes to single casting
- Reduced aerodynamic wind steps in annulus
