Comment on: “Review of Pyrotechnics” that appeared in Issue 18, Winter 2003
Ron Lancaster In the late 1960s there was only Weingart’s Pyrotechnics, and it was a suggestion of a rewrite to the Publisher that led to my own first edition in 1972. As we have grown in experience there have been two further editions. It has been interesting to see how many little bits of new …

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 …

A Brief Description of the Construction and Function of Common Electric Matches
Lawrence Weinman and K. L. Kosanke ABSTRACT: A simple description of the construction and the physical principles governing the function of common electric matches and some implications of these principles for testing and firing them are presented. Keywords: electric match, heat resistance, current, volt, pyrogen Ref: JPyro, Issue 19, 2004, pp66-71 (J19_66)
Bandwidth in Electro-Magnetic Compatibility (EMC) Testing
James Stuart ABSTRACT: Electro explosive devices (EEDs) are often required to undergo a test in which they are placed near a high-power radio transmitter. The purpose is to see whether electromagnetic energy might fire the EED. Consideration of the “Q” or quality factor of an EED system affords guidance in choosing a transmitter and test …

Illuminants and Illuminant Research
David R. Dillehay ABSTRACT: The use of pyrotechnic compositions for the production of light has a long history. Most improvements were made mainly by trial and error with many misunderstandings about the cause and effect relationships from observations. Significant advancements in the mechanisms and theory of combustion have increased the understanding of many effects and …

A Report on the Fireworks Accident at Carmel, Western Australia
R. I. Grose and K. L. Kosanke ABSTRACT: The investigation into an accident at Carmel, Western Australia in March 2002 found that the magnitude of explosions occurring in licensed and unlicensed storage areas was significantly greater than would have been expected from the UN hazard classification of items stored within them. Use of revised UN …

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 …

Guanidinium Azo-Tetrazolate (GAT) as a High Performance Hybrid Rocket Fuel Additive
M. Keith Hudson, Ann M. Wright, Chris Luchini, Paul C. Wynne, and Sterling Rooke ABSTRACT: The purpose of this investigation was to find a high regression rate fuel suitable for use as a mixture with hydroxyl-terminated polybutadiene (HTPB). Guanidinium azo-tetrazolate (GAT) is the compound that was the focus of our research. GAT is a salt …

Essential Molecular Orbital Theory for the Study of Pyrotechnics
R. B. Lowry ABSTRACT: The Linear Combination of Atomic Orbitals (LCAO) model is presented as it applies to small heterogeneous molecules. A non-mathematical approach is used to enable the discussion of the terminology used. The production of light and the rules that govern it are examined. Keywords: linear combination of atomic orbitals, LCAO, energy level, …
