Paramotor propeller 1.30 m, 3 blades (rounded tips)
Model designed and computed with the Heliciel software. Design point: 2,718 rpm at 40 km/h (185 cc paramotor engine at 7,800 rpm, 2.87 reduction). Rounded tips. A propeller is a dangerous object, in particular because of the risk of bursting under centrifugal force. These files result from theoretical assumptions and are supplied without any guarantee of operation. These models must be tested and validated in conditions that cannot endanger human life; a propeller tested and validated by a professional may then be used.
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.
