Abstract
In this phase of the project, a number of attempts were made to see if the flaming tendency of the cinnamic acid composition developed at DREV could be controlled. These included: (a) the use of other cinnamic acid compounds, (b) providing porous castings for the smoke candles, and _ the use of flame inhibitors. Unfortunately, one of these efforts proved successful. A further set of experiments was conducted with a new white smoke composition based on ammonium chloride. These experiments demonstrated that a smooth burning candle producing copious amounts of white smoke can be fabricated using the new composition. Further, a new binder, which is available commercially as a glue, has been successfully tried in these experiments. This binder provides any degree of castability that is desired. It is much easier to handle than the currently used hydroxy-terminated polybutadiene (HTPB) which in fact is a rocket fuel binder. The work done during this final phase of the project is summarized in the third and final report on the project.
