Innovative aquatic firework assembly engineered to float and spin on a water surface 插畫檔

A detailed technical diagram illustrates the structural composition of a specialized maritime pyrotechnic device known as a girande d'eau, designed to create dynamic visual effects directly on lakes or rivers during public festivities. The apparatus features a floating cup-shaped basin mounted on a vertical support stem, rigged with a cluster of upright rocket drivers and interconnected horizontal propulsion cartridges linked by sequential quick-match fuses to ensure automated rotational thrust and a synchronized ignition sequence. Originating from France, this nineteenth-century instructional engraving reflects the advanced hydraulic and chemical engineering concepts published to document the precise manufacturing of specialized aquatic ordinances used for grand historical civic celebrations.
