aerospace flywheel 3d model

Design an ultra high-performance aerospace reaction wheel flywheel for robotic cube self-balancing (Cubli type). Structure with 7075-T6 aluminum hub and ultra-dense steel inertia ring. Outer diameter 120 mm, thickness 12 mm, hub bore 38 mm, total mass ≈ 240 g, with 80–85% mass concentrated in outer ring. Steel ring OD 120 mm, ID 108 mm, thickness 6 mm, precision turned, press-fit into aluminum core for maximum inertia radius. Aluminum hub topology-optimized skeleton with 6 ultra-thin I-beam spokes, width 4.5 mm, web 2 mm, height 8 mm, each spoke with large elliptical weight pockets 14×5 mm. Motor mount 4×M4 holes on 25 mm PCD with light countersink. Add 3 M3 dynamic balancing holes at 120° on radius 57 mm depth 5 mm. Include laser engraved 0° reference mark radius 58 mm depth 0.2 mm. All edges 0.5 mm chamfer, internal fillets ≥1.5 mm, CNC machinable with 3 mm tool, pocket depth 3 mm. Perfectly symmetric aerospace mechanical CAD flywheel optimized for extreme rotational inertia
