Design a highly efficient 3-bladed propeller with a circular tip ring (tip-connected frame). Geometry requirements: • Exactly 3 blades, evenly spaced at 120° • A central hub with a precise 4 mm diameter cylindrical hole, perfectly concentric • A thin circular ring/frame connecting the outer tips of all three blades, forming a closed loop • The ring must be structural but lightweight, with uniform thickness and smooth curvature Blade design (very important): • Each blade should use a modern aerodynamic airfoil profile (similar to NACA low-Re airfoils) • Blades must have progressive twist: higher pitch near the hub, lower pitch near the ring • Smooth filleted transitions between: – blade ↔ hub – blade ↔ circular ring • Blades should be thin, slightly cambered, and optimized for high efficiency Ring design: • The circular ring should act as a tip-vortex suppressor • Inner edge of the ring should be smoothly blended with blade tips • No sharp edges anywhere on the ring Structural & manufacturing constraints:
