摘要
本文以Culick线性理论为基础,提出预估固体火箭发动机燃烧不稳定性的方法,并给出一个算例.讨论了提高微粒阻尼预估精度和考虑平均流动影响的问题.首次提出用统计方法评定燃烧不稳定性、给出发生燃烧不稳定概率的方法,并讨论了这种统计方法的合理性和可行性.
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.
