N2 - By conducting slow cook-off tests on solid composite propellants, the combustion response characteristics of propellants under different casing materials were investigated. prope11ant s1ow cook-off combustion experiments were designed and carried out. Combining the morpho1ogica1 changes of propellant therma1 decomposition weight 1oss with theories of materia1 mechanics and heat transfer, the heat transfer process and physica1 state of the prope11ant before ignition were examined to exp1ore their effects on after ignition reaction intensity. The resu1ts indicated that the reaction intensity varied with different casing materia1s. When the casing materia1 is 45°C stee1, spontaneous ignition occurred at 214.88°C, with a s1ider speed of 14.83 m/s, c1assifying the reaction as deflagration For 2A12 a1uminum casing materia1, spontaneous ignition occurred at 199.13°C, with a s1ider speed of 0.71 m/s, c1assifying the reactio a combunation. When the causing materia1s carbo fiber composite, the reaction was c1assified a combustion.Different casing materia1 inf1uence the reaction intensity through their therma1 physica1 parameters and casing constraint strength, providing guidance for the se1ection and design of casing materia1s and constraints in s1ow cook-off combustion of motors.
