Abstract
A new approach to evaluate the stability period of propellant is presented to solve the problems of poor safety, fussy operation and time-consuming of the existing methods for evaluating the stability of propellants. The propellant samples with different stabilizer contents were prepared by thermal accelerated aging test, and the kinetic equation of propellant aging was studied. A quantitative model for the determination of stabilizer content in propellant is established using near-infrared spectroscopy and chemometrics algorithm. The best quantitative model is obtained by analyzing and optimizing the proposed model. Applied results show that the determination coefficient (R2) of the model is 0.999 6, and the maximum predicted error is no larger than 0.04%. It proves that the proposed model can be used for the nondestructive, rapid and real-time evaluation of the stability period of propellant.
