Pyrotechnic Whistles
W. R. Maxwell Introduction: The fact that certain pyrotechnic compositions when pressed into a tube and ignited burn with a loud whistling noise has been known and used by firework manufacturers for many years. The two compositions most widely employed appear to be (a) a mixture of dry powdered potassium picrate and potassium nitrate in …

Progress in Developing a Fuel-Air Salute
Fred Ryan ABSTRACT: In a fuel-air salute a fine metallic fuel is first dispersed into the surrounding air, then ignited. Such a salute is much safer than a conventional salute as the salute fuel must be mixed with air to obtain the oxygen needed to function. It can not explode violently in bulk or in …

Evaluation of Fire and Explosion Hazards for a Non-Azide Gas Generant
Kazuo Hara, Mitsuhiro Kanazawa, and Tadao Yoshida ABSTRACT: A hazard evaluation has been carried out for the safety assessment of a new non-azide gas generant for automotive airbag inflators. The gas generant (UN) is composed of urazole (U) and a metal nitrate (MNO3;N) with other additives included to provide the required performance. The impact, shock, …

Flash Powder Output Testing: Weak Confinement
K. L. and B. J. Kosanke ABSTRACT: A variety of flash powders were tested under weak confinement to determine the sound pressure levels and tonal characteristics produced. In these tests it was found that: the sound output from mixtures prepared with potassium perchlorate from four manufacturers are essentially equivalent; there are significant differences in the …
