Abstract
A flash-bang projectile that generates one or more noise pulses and one or more flashes of light. In generating a noise pulse, the flash-bang projectile provides a housing that includes a gas chamber that entraps air. The gas chamber includes a compression device that, when the flash-bang projectile is shot or otherwise ejected by a gun or other form of ejection device, compresses the air that is entrapped in the gas chamber. A burst disk forms one wall of the gas chamber and is configured to rupture a selected time delay after the air has been compressed. Rupturing of the burst disk releases the compressed air entrapped in the gas chamber, allowing the air to be released through a horn nozzle, thereby generating a noise pulse. The flash-bang projectile may have more than one gas chambers, with associated compression devices, whose burst disks are configured to rupture with diverse time delays, in which case the flash-bang projectile can generate multiple noise pulses with corresponding delays. In generating a light flash, the flash-bang projectile includes one or more light generating devices, which may include items such as flash lamps, light-emitting devices, and the like, along…
