Fourier Transform Infrared Spectroscopy (FTIS). Volume I. Technical Report.
Abstract
This is the final report of a contract to establish the relationship between infrared spectra and propellant aging and to determine the applicability of this relationship to the prediction of service life of propellants. Equipment for measurement of infrared specta by both attenuated total reflectance and through transmission was identified, and procedures for sample preparation and testing were developed and demonstrated. Computer programs for reducing the infrared spectra data and statistically analyzing them were developed and made operational on the CDC 6600 computer at the Air Force Rocket Propulsion Laboratory. Aging programs were conducted for two composite solid propellants, and the correlations between their infrared spectra and tensile properties as aging progressed were determined. Equations were established for the prediction of future tensile properties from spectral properties acquired during aging. The major accomplishments of this project are the establishment of methods for predicting propellant tensile properties from infrared spectral data during storage and the development of procedures and computer programs for rapidly and economically processing large amounts of infrared data. The results of this project are a major step toward predicting the remaining shelf life of solid propellant rocket motors from infrared measurements using small amounts of propellant associated with them. Recommendations for application of these results and for improving and extending the developed methods are included in the report.
