Heliciel — Propeller & Wing 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 professionals and hobbyists have used for 15+ years. WHAT YOU CAN DESIGN: aircraft propellers, drone and 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 or chord distribution — deterministic sweep or genetic search, always within bounds you choose.
• Check the physics: cavitation, blade-passing frequencies, design alerts, hydraulic head balance for ducted turbines.
• Show results: images of the blade, the screen and the charts, brought into the conversation; plus an interactive 3D viewer, opened from a link, where you can rotate the blade and pick an element to read its profile.
• 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 for, never assumed; values inherited from the loaded model are flagged as such; a failed computation is reported as-is, with Heliciel's own design alerts. REQUIREMENTS: a Heliciel MCP pass (day, week or month) from mecaflux.com. You connect once with OAuth: paste your pass key on our consent screen, and nothing more to enter afterwards.
