Abstract

Solid rocket motor propellant in the long-term storage process of the drug column structure damage has the characteristics of strong concealment, great harm, and difficulty to detect. At present, for the structural health monitoring technology of solid rocket motor propellant, a large number of studies have been carried out abroad, and related research has been carried out in China. In this paper, the relevant concepts and connotations of solid rocket motor propellant structural health monitoring technology are sorted out, the performance of the main methods of current solid rocket motor propellant health monitoring technology is compared, and the research status of emerging structural health monitoring technologies such as piezoelectric impedance method, fiber grating method and infrared thermal imaging method is analyzed. In this paper, based on the current research status, the possible development direction of future research is explored and prospected.
