Аннотация: A dependence of the burning rate of solid energetic materials on the burning surface curvature is investigated. The model predicts an existence of a limiting value of curvature above which self-sustained combustion is impossible. This result is used for explaining the critical conditions of combustion of homogeneous condensed energetic materials. The critical combustion diameters of several homogeneous energetic materials are calculated and compared with experimental data. A combustion model for mixtures of energetic binders with inert and active fillers which takes into account the curvature of the burning surface of the binder layers and ignition delay of the filler is developed. A parametric study of the proposed model was performed over a wide range of particle sizes of the filler, its concentration in the mixture, and burning rates of the binder. The results of the model were compared with experimental data for mixtures of energetic binders with SiO2, HMX, AP, and CL-20. A unified dependence of the ignition delay of HMX, AP, and CL-20 particles on their size, the burning rate of the mixture, and the thickness of the binder layers is proposed. The model is used for calculation of temperature sensitivity of the burning rate of propellants based on energetic binders.
