Fireplay

David Howard Abstract: ‘‘Fireplay’’ is a generalist overview of pyrotechnics. It is indebted (and acknowledges its debt) to seminal works such as Brock’s ‘‘History of Pyrotechnics’’ (1949), yet develops an aesthetic – even metaphysical – discussion of the key question for our profession: ‘Why do fireworks move people?’ Keywords: History, aesthetics, gunpowder Ref: JPyro, Issue …

A Thermokinetic Model for the Combustion of Strobe Composition

Matthew L. Davies Abstract: A model chemical reaction scheme, in which a substance undergoes a two-stage decay process, is developed. It is shown that this reaction scheme follows the Shimizu hypothesis for pyrotechnic strobe combustion; both decay stages are temperature dependent with only the second generating a significant quantity of heat. The model is derived …

Movement Dynamics Of Firework Shells Fired From Mortars

V. Ya. Yakovlev and S. K. Chankaev Abstract: Experimental investigations were carried out using 125 and 310 mm firework shells. The pressures in a mortar during firing were measured. A mathematical model of the firing action concerning low pressure in the space behind the shell was developed. Here it is supposed that non-simultaneous processes of ignition …

Comparison of 6-DOF Trajectory Model with Modified Linear Theory for Bullets

Dimitrios N. Gkritzapis, Elias E. Panagiotopoulos, Dionissios P. Margaris and Dimitrios Papanikas Abstract: A modified linear model is proposed for fast and accurate prediction of short and long-range trajectories of spin-stabilized bullets via atmospheric flight to a final impact point. This model is compared with a full 6-DOF trajectory model. The computational flight analysis takes …

The Debris Hazard from Fireworks Held in Steel ISO Containers

Roy Merrifield and Peter Allan Moreton Abstract: A number of serious accidents in European Union countries involving explosions of fireworks stored in steel ISO freight containers has shown that the hazards associated with bulk-stored fireworks might be greater than previously thought. To address this problem an EU research programme was initiated, part of which involved …

Copper in Pyrotechnics

Georg Steinhauser, Karina Tarantik and Thomas M. Klapötke Abstract: Copper compounds play a key role in the development of “greener” pyrotechnics by substitution of noxious barium compounds from green colored effects. The application of many copper(ii) compounds in pyrotechnics is limited because of their noble and often hygroscopic character. We have investigated nitratocuprates(ii) as well …
