A boat propeller with a bored hub and N adjustable airfoil blades, each blade surface created via interpolation of 5 sparse NACA-style control sections. The blade recipe (airfoil ring → chord/twist schedule → smooth loft → radial placement) serves as the foundation for adapting to fans, impellers, and airplane props. Adjustable parameters include blade count (2–6), span, root/tip chord, twist/washout, thickness, camber, and handedness for counter-rotating pairs; hub diameter and bore diameter complete the design.
Designed by Scott in PartForge, parametric CAD with an AI collaborator.
