Thermal Conductivity Testing of Minimal Volumes of Energetic Powders

Adam Harris and Daniel N. Sorensen Abstract: Safety constraints have traditionally presented researchers with challenges in testing the thermal conductivity of energetic powdered materials. Minimal volumes of energetic powders can now be tested with the modified transient plane source technique. The newly modified sensor design further reduces the possibility of impact, friction and electrostatic discharge (ESD) …

Survey of Firework Trends from UK Display Companies

Tom Smith and Avril di Palma Abstract: As part of CarnDu’s involvement with the UK firework display industry, a survey of UK professional firework display companies was carried out to identify areas of current concern and to attempt to identify trends. The results of this survey are presented here. Keywords: Survey, 2007, fireworks, UK Ref: …

Evaluation Of Multi-shot Firework Articles Using Mortar Recoil Measurements

R. Guilbeault and E. Contestabile   Abstract: Recoil from fireworks articles often arises as a concern in accident investigations or when fireworks are launched from unconventional locations such as rooftops, or other light building elements such as overhangs, from decks of small bridges or those of barges. In this latter case, the Authority Having Jurisdiction …

Exterior Ballistics of Firework Stars

Yuzo Ooki, Dayu Ding, Morimasa Higaki, and Tadao Yoshida Abstract: Burning and shot experiments have been carried out to examine the burning time and the trajectory of burning firework stars. The burning time in flight was longer than the stationary burning time. The trajectory of a burning star in the air was modeled assuming the …

Burning Characteristics of Firework Stars and Lifting Charge

Morimasa Higaki, Dayu Ding, Yuzo Ooki, and Tadao Yoshida Abstract: Burning experiments were carried out for stars and lifting charge in the air and in a closed vessel. Three types of stars were used, that is, ordinary spherical, half-restricted spherical and hemispherical surface-restricted stars were used as models for flying burning. Partly restricted stars gave …

Spectroscopic Measurement of Burning Toy Fireworks

Kazuomi Itoh, Dayu Ding and Tadao Yoshida Abstract: The spectroscopic measurement of sparklers, torches and senko hanabi (Japanese sparklers) was  carried out. The three dimensional spectra of sparklers and torches showed that the peak intensities of the spectra fluctuate with time. In the burning of sparklers, white, titanium, senko and iron sparklers showed mainly the …

Tests for Evaluating the Ignitability of Firework Stars and Compositions

Yasuhiro Sashimura, Mamoru Horiuchi, Hideo Watanabe, Maiko Watanabe, Dayu Ding and Tadao Yoshida Abstract: A shot test was examined for evaluating the ignitability of cylindrical bare and primed stars. The primed stars were more easily ignited than the bare stars. The ignition limit lift charge was defined and used for evaluating the ignitability. Though the …
