In this work we investigate the linear stability of combustion waves propagating in a system of two layers of different exothermic reacting materials under conditions of thermal contact between them through the common interface using the reaction sheet approximation. The dispersion relations are found and the dependence of the stability boundary on the parameters of the model is studied. It is demonstrated that the boundaries of stable combustion wave propagation in such system can be significantly extended if the properties of the layers are properly tailored.

燃烧波在两个热耦合薄固体燃料层中传播的稳定性

在这项工作中，我们研究了燃烧波在两层不同放热反应材料的系统中传播的线性稳定性，在它们之间通过公共界面热接触的条件下，使用反应片近似。找到了色散关系，研究了稳定性边界对模型参数的依赖性。结果表明，如果适当调整层的特性，则可以显着扩展此类系统中稳定燃烧波传播的边界。
