Wageningen B-series marine propeller B6-80, P/D 0.6 – 6 blades, Ø 600 mm
Model designed and computed with the Heliciel software. Design point: 400 rpm at 1.80 m/s (3.5 knots), J = 0.450, sea water. Exact geometry of the Wageningen B6-80 B-series at P/D 0.6: six blades, segmental sections and constant pitch, as on the K_T-K_Q charts. The model scales: the series is geometrically similar at any diameter.
The pack contains the complete propeller as a full-definition STL with root fillet, STEP surfaces (complete propeller and one blade), the Heliciel .hlc project and the computation records.

This model was designed and computed with the Heliciel software. For a custom propeller there are two ways: the Heliciel software (Windows: computation, 3D view, STL and STEP exports), and the Heliciel MCP connector, which lets your AI assistant — ChatGPT, Claude, Le Chat and any MCP client — compute a real propeller, with a free 1-day discovery pass.
