Special Materials in Pyrotechnics Part 2.[55] — Application of Cæsium and Rubidium Compounds in Pyrotechnics
Ernst-Christian Koch ABSTRACT: The application and thermochemical behavior of pyrotechnics based on rubidium and cæsium compounds are reviewed. Keywords: alkali metal, cæsium, pyrotechnics, rubidium Ref: JPyro, Issue 15, 2002, pp9-24 (J15_09)
Evaluation of the Hazards Posed by High Energy Bangers Part 1. Noise, Overpressure and TNT Equivalence
R. K. Wharton, D. Chapman and A. E. Jeffcock ABSTRACT: The work reported in this paper was undertaken to determine the hazards posed by certain types of European bangers (firecrackers) that use flash composition. Experiments were done to evaluate the overpressures and noise levels close to such fireworks when they function. The results indicate that …

Application of Hydroxyl (OH) Radical Ultraviolet Absorption Spectroscopy to Rocket Plumes
M. W. Teague, Tonya Felix, M. K. Hudson, and R. Shanks ABSTRACT: A spectrometer system was constructed for measurement of transient species in flames by absorption of ultraviolet radiation. The output of a xenon arc lamp was used as the source of radiation, which was focused through the flame and onto a monochromator equipped with …

The Effects of External Fire on Fireworks Stored in Steel ISO Transport Containers
S. G. Myatt ABSTRACT: The increased use of steel ISO transport containers for storing fireworks led the UK’s Health and Safety Executive (HSE) to commission research to gain a better understanding of the behaviour of fireworks in such storage when exposed to an external fire. Subsequent incidents involving storage of fireworks in ISO containers demonstrated …

Effect of Ultrasound on Single-Base Propellants for Pyrotechnic Purposes
Valentin Grozev, Radi Ganev, Ivan Glavchev ABSTRACT: Investigations were conducted on the effect of ultrasound on single-base propellants. Changes in the average viscosimetric molecular weight of nitrocellulose in the solutions of propellants in acetone and in a mixture of ethyl alcoholdiethyl ether were studied. It has been established that, for at least 60 minutes, the …

Thermodynamics of Black Powder and Aerodynamics of Propelled Aerial Shells
John E. Mercer ABSTRACT: This paper describes the theoretical basis of a computer code that numerically models firework mortars. The code analyzes both the Black Powder propelling and flight segments of a shell. Equations for the gas dynamics of Black Powder combustion, leakage flow around the shell and aerodynamics of flight are included. Representations for commonly …
