- Abstract
Azide polyether propellant is a new type of high‐energy solid propellant with broad application prospects. In order to measure the mechanical properties of azide propellant, tensile tests of propellant under different loading conditions were carried out, and compression test pieces of azide propellant of different sizes were designed and tested, and the tensile and compressive stress‐strain curves of azide propellant were obtained. Through qualitative and quantitative analysis, the influence law of loading rate and temperature on the mechanical properties of propellant was obtained, the linear variation law of mechanical properties parameters with logarithmic strain rate was analyzed, and the mathematical relationship between propellant stiffness and strength was found. The master curve of the compressive initial modulus and maximum strength of the azide propellant was drawn. The test results can provide theoretical basis for the performance research of azide propellant and the nondestructive testing of this type of engine.
