Kaplan turbine runner 500 mm, 8 blades (37 m head)
Model designed and computed with the Heliciel software. Design point: 37 m net head, 2.176 m³/s flow, 1278.5 rpm (hydraulic power 790 kW). Specific speed from the turbine selection chart (Ns 417 at 37 m head), diameter and hub from the Kaplan statistics; runner balanced on the head by Heliciel's hydro turbine study.
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.
