CAD / 3D Modeling
High-Speed Turbomachinery Impeller
Developed complex multi-splitter blade geometry for high-efficiency aerospace micro-turbines operating at extreme centrifugal stress states.
CATIA V5 TurbomachineryANSYS BladeGenCFD Flow-3D5-Axis CNC
3D CAD RENDER // EXPLODED STRUCTURAL VIEW
Engineering Challenge
High centrifugal forces at 85,000 RPM caused blade tip elongation and housing rubbing.
Applied CAD & DFM Solution
Applied aeromechanical coupled stress-deformation lofts to pre-compensate for thermal and centrifugal blade growth under operating speed.
Key Modeling & Surfacing Highlights
Parametric blade section lofting using NACA airfoil coordinates
5-axis CNC tool collision clearance volume generation in CATIA
Dynamic spin burst protection wall thickness calculation
