CATIA V5 TurbomachineryANSYS BladeGenCFD Flow-3D5-Axis CNC

01 // ISOMETRIC 3D CAD RENDER

01 // TECHNICAL CHALLENGE

High centrifugal forces at 85,000 RPM caused blade tip elongation and housing rubbing.

02 // ENGINEERING & DFM SOLUTION

Applied aeromechanical coupled stress-deformation lofts to pre-compensate for thermal and centrifugal blade growth under operating speed.

03 // MODELING & TOLERANCING 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
