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 …

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 …

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 …

Dayu Ding, Morimasa Higaki, Yozo Ooki and Tadao Yoshida* Abstract: The burning time of stationary and flying fireworks stars was measured, the trajectories of flying stars were observed and the results were analyzed in this work. It was found that the difference in burning time between the stationary and flying burning stars was dependent on …
