Heliciel Propeller Design

Heliciel turns your AI assistant into a propeller and turbine design engineer. Instead of plausible-looking guesses, every number comes from a real BEM (Blade Element Momentum) computation run by the Heliciel engineering software — the same solver used by hobbyists and professionals for 15+ years.

What you can design: aircraft propellers, drone/multirotor propellers, marine propellers, axial fans, wind turbines, hydro turbines (including ducted Kaplan runners), wings and hydrofoils.

What the AI can do with it:

• Size a propeller from your specification (power, speed, thrust, diameter, blade count) — the design RPM is searched automatically to hit your target.
• Analyze off-design behaviour: operating-point performance, sweep curves (power vs wind speed, efficiency vs RPM), 2D performance maps.
• Optimize: RPM, blade count, tip radius, chord distribution — iterative or genetic search, always within bounds you choose.
• Check physics: cavitation (marine), noise indicators, blade stress warnings, hydraulic head balance for ducted turbines.
• Show results: interactive 3D viewer embedded in the conversation (rotate the blade, pick an element, read its profile), performance charts, design alerts.
• Export for manufacturing: STL (3D printing/CFD), IGES (CAD), OBJ, blade sections (JSON), analysis tables (CSV).

Honest by design: the server refuses to invent values. Missing parameters are asked, not assumed; inherited model values are flagged; failed computations are reported as-is with Heliciel's own design alerts.
