| Abstract: | The rating of dynamical combustion stability is one of the important approaches for the stability assessment. The stability rating contents for a certain rocket engine is elaborated according to the relative information about the rating research of dynamical combustion stability for liquid rocket engines at home and abroad. The characteristics of disturbance methods, dynamical pressure testing and stability diagnosis are analyzed emphatically in combination with the criteria of stability rating based on CPIA655. The advantages and disadvantages of each method are pointed out. The key tech- nology and basic criteria of dynamical combustion stability rating are proposed. |
