EVALUATION OF NEW PHOTOFLASH FORMULATIONS.
Abstract
Photoflash sysems containing hafnium and potassium perchlorate in stoichiometric (72/28), fuel rich (77/23, 82/18), and calculated maximum efficiency (87/13) proportions generally exhibit greater luminous efficiency on a volume basis (candleseconds per cubic centimeter) then the conventional 60/40 potassium perchlorate/aluminum and Type 3, Class A photoflash formulations under either ambient conditions or reduced pressure conditions simulating an 80,000-foot altitude. With increased hafnium content, greater integral light and volumetric efficiency values are obtained under either ambient or high altitude conditions. Under reduced pressure conditions, the stoichiometric hafnium/potassium perchlorate system and a ternary blend of hafnium/potassium perchlorate/barium nitrate (72/14/14) gave superior peak light intensity values when compared with the above conventional formulations as well as the optimum high altitude flash system of 80/20 calcium/potassium perchlorate.
