Roy Merrifield ABSTRACT: Large quantities of a whole range of materials, including fireworks, are moved around the world in steel ISO containers. In recent years in the UK, manufacturers and retailers have used such containers to store fireworks. It has been long recognised that confinement can increase the hazard of energetic materials such as pyrotechnics …

Prediction of Flame Temperatures, Part 1: Low Temperature Reactions
Daniel P. Dolata, Thomas I. Perigrin ABSTRACT: A method based on heat of reaction and heat capacity at constant pressure (ΔHr and CP) was devised for the prediction of flame temperatures for simple “low temperature” pyrotechnic reactions containing either potassium chlorate, potassium perchlorate, potassium nitrate, or ammonium perchlorate (KClO3, KClO4, KNO3, or NH4ClO4) as the …

An Introduction to PROPEP, A Propellant Evaluation Program for Personal Computers
Edwin D. Brown ABSTRACT: Propellant evaluation programs are used to estimate the performance of rocket propellants, to compare the performance of different propellants, and to evaluate the effects of formulation changes. While the program output may not be exact, it compares well with experimental results. Their major weakness lies in the accuracy and completeness of …

An Introduction to Chemical Thermodynamics Part 3. Free Energy and Equilibrium
Barry Sturman ABSTRACT: This is the third article in a series presenting an introduction to chemical thermodynamics, emphasizing those aspects of particular relevance to pyrotechnics. It shows how the Gibbs free energy varies with temperature and pressure, and how this affects chemical equilibrium. It also shows how a number of useful facts about chemical systems …

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 …
