| Abstract: | Based on Culick's linear theory, this paper, proposes a method for predicting the combustion Instability in solid rocket motors, and provides an example of the prediction calculation. It discusses especially how to increase the calculation accuracy of particulate dampiny and how to deal with the influence of high-speed mean flow. This paper is the first one which proposed a statistical estimation of the combustion instability and a method of probability calculation. It also discussed the rationality and the feasibility of the statistical method. |
