Description
Summary:A study was made of combustion mechanisms of composite solid rocket propellants, using the sandwich burning method to minimize the statistical aspects of experimentation and interpretation of results inherent in propellant studies. The results provide a more clear picture of the complex combustion process than has been possible previously. Because of the importance of knowledge of the decomposition mechanisms of individual propellant ingredients at combustion zone temperatures, a combination of facilities was planned for studies of this subject. The primary effort under the contact was development of a new thermal analysis instrument that can measure weight change as a function of time while heating a sample at 100C/sec. Heating may be done by laser, furnace, or radio frequency induction. The test sample is deposited on the free end of a rod that vibrates during a test, and mass change is determined by recording the change in vibration frequency of the rod. Results are reported comparing the decomposition behavior of two propellant binders as measured by this high rate thermogravimetric analyzer and a conventional TGA.
