Heliciel · Shop Français

Explore the shop by query: the tool for AI assistants

The shop offers 410 propellers, rotors and turbine runners, all designed and computed with the Heliciel software. This page describes an open HTTP endpoint, with no key or account, that an AI assistant or agent (ChatGPT, Claude, Perplexity, a custom GPT, a browsing agent…) can call to answer a request such as “show me a propeller for my project”: it receives the models closest to the given parameters, with their page, their 3D view and their computed values.

The tool computes nothing: it ranks the existing models by their values at the design point, using the mean logarithmic deviation between the requested values and the model's (the same ranking as the “closest model” filter of the category pages). When no model is close, it says so and points to the two custom routes: the Heliciel software and the Heliciel MCP connector.

Address

https://www.heliciel.com/boutique-modeles-3d/explorer.php — GET request. Without parameters the response describes the tool (parameters, categories, examples). OpenAPI description: /boutique-modeles-3d/openapi.json; summary for agents: /en/llms.txt.

Parameters

NameTypeMeaning
typestringCategory: drone, avion, bateau, eolienne, hydrolienne, kaplan, ventilateur, pompe. Optional: without it, the whole shop.
qstringFree text searched in the reference and the title (e.g. B4-70, 13x17, winglets).
nb_palesintegerRequired number of blades (strict filter).
sensstringRequired direction of rotation: droite (right-hand) or gauche (left-hand) — strict filter.
diametre_mmnumberDesired diameter in mm.
pas_mmnumberDesired pitch at 0.7 R in mm (propulsive propellers).
regime_trminnumberRotation speed in rpm.
vitesse_msnumberFluid speed (advance, wind, current) in m/s; also vitesse_noeuds (knots) and vitesse_kmh (km/h).
poussee_nnumberDesired thrust in N (propulsive propellers).
puissance_wnumberShaft power in W (available motor power, or recovered power for a turbine).
chute_mnumberNet head in m (Kaplan turbines).
debit_m3snumberFlow rate in m³/s (Kaplan); also debit_m3h in m³/h (fans, pumps).
pression_panumberPressure rise in Pa (fans, pumps).
nintegerNumber of models returned, 1 to 5 (default 3).
langstringfr or en: language of titles, labels and page addresses.
formatstringjson for the JSON response (or Accept: application/json header); otherwise readable HTML.

nb_pales and sens filter strictly; the other quantities rank. A model carrying none of the requested quantities is discarded; those it lacks are listed in criteres_manquants.

Response

In JSON: demande (parameters as understood), nb_resultats, modeles — for each sku, titre, categorie, gamme, page (full product page), page_3d (the page with the 3D viewer open), vignette, prix_ttc, gratuit, cotes (diameter, blades, pitch, hub, bore, direction), point_de_calcul (speed, fluid speed, thrust or axial force, torque, power, efficiency or Cp, pressure rise, head, flow), caracteristiques (every line of the product page), ecart and correspondance (proche, approchante, eloignee) — then note (method and limits) and aller_plus_loin (shop, software, MCP connector, discovery pass). Field names are French identifiers; titles and labels follow lang.

All values are those computed by Heliciel at the model's design point, as listed in the catalogue: the tool does not extrapolate and invents no figure. Each product page carries a similarity calculator for another speed, within the computed range.

Categories and value of the type parameter

Limits and proper use

At most five models per call, sixty calls per hour and per address. The models are computed geometries supplied without any guarantee of operation (see the terms of sale): the assistant must report the values as “computed by Heliciel at the design point”, never as measurements. For a propeller with other parameters, the Heliciel MCP connector has the software compute a real design.

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.

What you receive

A .zip archive: full-definition STL, STEP, Heliciel .hlc project and description sheet. The download link is also sent by e-mail.

Safety

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.
