Development of a low-smoke lift system for fireworks shells
conference paper
For launching firework shells, typically a black powder lift charge is applied. A drawback of this charge is the production of ground smoke, having both a visual and an environmental effect. To reduce this smoke, TNO has developed a low smoke lift system for firing 3 inch fireworks shells. Requirements included, besides low smoke evolution during launch, high reliability and a weather proof design.
Nitrocellulose forms the basis of modern gun powders and as such has proven to be capable of smokeless launching of projectiles. However, as the combustion of nitrocellulose is strongly pressuredependent, a high pressure chamber would be required for efficient utilization of nitrocellulose as a propellant. Such systems are relatively common for mortars in the defense industry but are rarely used for pyrotechnic applications.
In this paper the development of a low-smoke lift system for fireworks shells is described.
