A standard catalogue model: the dimensions, control package and finish are fixed, which is what keeps the price and the lead time predictable. Size, colour and interface language can be adapted without a new design cycle.

01 / Overview

The exhibit adopts an interesting interactive approach, where visitors drives the fan blades to rotate by stepping on the pedal, and intuitively understands the scientific principles of propeller motion.

02 / How visitors use it

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.

03 / The science behind it

A propeller refers to a device that rotates in air or water by means of propeller blades, converting the rotational power of an engine into propulsive force. It can have two or more blades connected to a hub, and the backward side of the blades is a helical surface or approximately helical surface, which is a type of marine propeller.

04 / Built for a public floor

Every unit leaves the factory after a running test: mechanisms cycled, electronics burned in, edges dressed, fixings torqued and marked. Wear parts — bearings, sliders, lamps, belts, touch panels — are modular and listed on the spare-part sheet, so a venue technician can replace them without returning the exhibit. Crating is plywood with foam blocking; the loading plan and packing list travel with the shipment.
