- Аннотация: A stable algorithm of structural and parametric identification of combustion dynamic characteristics from the results of experiments with registration of the current burning front position has been developed, which allows prediction of current values of burning rate u(τ) and its frequency response with accuracy acceptable to practice. The proposed approach has been tested by simulation calculations with harmonic input signals, including superimposed noise of different intensity, to determine the accuracy of identification of the amplitude and phase frequency characteristics of burning. The approach has been used to study dynamic combustion characteristics of a model propellant under oscillating pressure. The transfer and response functions have been determined for a low frequency area. It has been shown that the approach is favorably distinguished from other procedures by higher accuracy and authenticity of estimations.
