Two-blade tidal turbine rotor 500 mm (Heliciel model)
Model designed and computed with the Heliciel software. Design point: 2.4 m/s current, 582.4 rpm (tip speed ratio 6.35). Fast two-blade rotor scaled from the 16 m tidal turbine supplied as a model with Heliciel (NACA 64-418 section), at the same tip speed ratio.
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.

Need a propeller for your own parameters?
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.
