A Prediction of Aerial Shell and Comet Trajectories Using SHELLCALC©
John Harradine and Tom Smith Abstract: This paper describes a model for predicting the path of aerial shells and Roman candle comets. This model, incorporated in a Microsoft® Excel-based freeware program, SHELLCALC©, predicts the trajectoryof these fireworks using point mass equations for range and height. These equations are modifi ed to take into consideration mortar/candle …

Ballistics of a No. 3 Spherical Shell with Illuminant
Dayu Ding, Y. Ooki, M. Higaki and T. Yoshida Abstract: Shot experiments were carried out using a No. 3 spherical shell with an illuminant. The three dimensional trajectory of the flying shell was obtained by tracing the shell with two high-speed video cameras in different orientations and by analyzing the recorded video picture. The 3DSTAR1 …

Ballistics of an Iron Bar Shot from a Mortar
Morimasa Higaki, Dayu Ding, Yuuzo Ooki and Tadao Yoshida Abstract: An accidental explosion in 1848 in the USA became a trigger for the development of neuroscience. An accidental explosion of black powder took place in a borehole for blasting and the expelled iron bar penetrated the head of a young man. He was injured but …

Temperature measurements within the luminous region of a burning Ba(NO3)2/Al mixture
P. J. Disimile, R. Prasad and N. Toy Abstract: Knowledge of the local temperature field associated with a pyrotechnic event has numerous implications, especially in the field of safety and survivability. These implications involve the development of sensors that are capable of detecting pyrotechnic events and that are used in part to eliminate or reduce …
