Complex pyrotechnic wheel laced with interconnected drivers engineered to spin and create geometric fire patterns 插畫檔

A detailed technical diagram illustrates the intricate structural assembly of a multi-stage rotating firework wheel mounted on a central axle pivot. The circular wooden frame is meticulously rigged with dozens of paper-wrapped powder drivers and quick-match fuses arranged in overlapping geometric configurations to trigger sequential thrust and concentric visual effects upon ignition. Originating from France, this nineteenth-century engineering illustration showcases the sophisticated design principles and manual fuse-linking techniques used by master pyrotechnicians to choreograph complex mechanical movement and dazzling light displays for major civic celebrations.
