Multi-blade wind rotor 1 m, 11 blades (pumping, slow speed)
Model designed and computed with the Heliciel software. Design point: 8 m/s wind, 230 rpm (tip speed ratio ≈ 1.5). Slow multi-blade rotor: high starting torque, suited to water pumping.
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.
