Mechanical Properties of Solid Propellants in Low Temperature Environments for Application to Planetary Exploration

Abstract

The mechanical properties of solid propellants at low temperatures are important for the use of solid propellants in planetary exploration. In this study, a simulated propellant in the glass transition state was compressed, and mechanical properties were obtained. The thermal contraction strain of a simulated propellant is discussed in terms of its materials. The residual strain that remained when the propellant was returned to room temperature may have been caused by particle migration.
