COMBUSTION MECHANISM OF HIGH BURNING RATE SOLID PROPELLANTS.
Abstract
Thiokol's program to tailor the burning rate of a propellant predictably and controllably to any desired level in the range from 1 to 10 inches per second is divided into three phases: Phase I - Synthesis of Burning Rate Catalysts, Phase II - Decomposition Studies and Evaluation of Catalysts and Phase III - Decomposition of Advanced Oxidizers, Fuels, and Binders. Experiments will be performed to synthesize more efficient burn rate catalysts by maximizing already determined guideline properties toward development of an ideal catalyst under Phases I and II. Following catalyst synthesis, each compound showing potential will be subjected to comprehensive decomposition studies and combustion mechanism evaluation with propellant ingredients. Effort conducted to date under Phases I and II indicate that esters of ferrocene carboxylic acid may be readily prepared in high yield; a convenient route to copper containing ferrocene derivatives has been discovered and utilized; ferrocene ethers may be prepared easily and in high yield, and acylation of ferrocene with methoxyacetyl chloride cannot be readily achieved. Of the catalysts synthesized to date, the following statements can be made in regard to compatibility with varied propellant ingredients: no compatibility problems are encountered with mixtures of the catalysts and HC polymer; the MAPO polymerization noted is only slightly accelerated in the presence of the catalysts, and no problems are expected in effecting good binder cures in the presence of the catalysts.
