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 …

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 …
