J. E. Fletcher ABSTRACT: The self-heating models of Frank-Kamenetskii and Thomas have been applied to predict self-ignition temperatures for sulfur-chlorate mixtures in spherical and cylindrical geometries of varying size. The models were validated by comparison to experimental cardboard tube test data previously reported. It was found that the Frank-Kamenetskii model, combined with kinetic data from …

Control Systems for the Storage of Explosives, Including Fireworks
M. J. Bagley ABSTRACT: This paper gives an account of the use of a questionnaire to obtain up-to-date information on control systems for the storage of fireworks and other types of explosives. The study showed that control systems for the storage of explosives based on quantity-distance schemes are used in many countries. In most of …

Assessing the Risks — Suggestions for a Consistent Semi-Quantified Approach
Tom Smith ABSTRACT: Assessing the risks of an operation, the operation of a whole factory, or the consequences of firing a firework display has become a way of life. Much modern legislation, certainly in the UK, is based less on “prescription” and more on “goal setting”, which requires the risk creator to determine the nature …

Thermal Characterization of Smoke Composition
Z. Abdel-Qader, Q. S. M. Kwok, R. C. Fouchard, P. D. Lightfoot and D. E. G. Jones ABSTRACT: The present work includes the thermal characterization of a smoke composition, the smoke components, as well as a potassium chlorate–lactose mixture using differential scanning calorimetry (DSC), thermogravimetry (TG), simultaneous thermogravimetry-differential thermal analysis-Fourier transform infrared spectrometry- mass spectrometry …

Color Values and Spectra of the Principal Emitters in Colored Flames
W. Meyerriecks and K. L. Kosanke ABSTRACT: The emission spectra of many of the more important emitters in pyrotechnic flames were collected. For this purpose solutions and suspensions of sodium, potassium, calcium, strontium, barium and copper salts were aspirated into a propane gas flame as the excitation source. Performing instrument corrections and using appropriate data …

Review of: Rocket Propulsion Elements, Seventh Edition – George P. Sutton, Oscar Biblarz
Rocket Propulsion Elements, Seventh Edition George P. Sutton, Oscar Biblarz Review by K. Koenig The seventh edition continues the high standards of this long-running text. The analysis, although a little sparse, is clearly presented. As in the previous editions, there is an abundance of figures and tables. And there is much information on practical design …

Fireworks Shells Subjected To a Modified Height-To-Detonation Test
E. Contestabile, R. Guilbeault, D. Wilson, and B. von Rosen ABSTRACT: Initiation of fireworks articles, as by a fire, can result in communication to adjacent articles and at times transition to a mass explosion. Such an event can be catastrophic. In a quest to discover the process by which this transition occurs and thereby work …

A Practical Performance Testing Protocol for Fireworks Mortar Tubes
Andrew Fischer ABSTRACT: The author’s development of an alternative design for a fireworks mortar coincided with the restructure of regulations concerning display fireworks in the State of Queensland, Australia. This new Code of Practice for the Display of Outdoor Fireworks has a requirement for manufacturers of equipment to develop performancebased tests that will prove the …
