| 摘 要： | 系统研究了铝镁贫氧推进剂低压燃烧性的表征方法。研究发现，低压下采用表压和绝压强所得到的燃速压强指数不同，用Summerfield燃速公式回归燃速与压强的关系比Vieille燃速公式更好一些。

| Abstract: | The characterization of the combustion properties of the aluminum-magnesium fuel-rich propellant for unchoked ducted rocket was studied. The pressure exponents calculated by the burning rates at different pressure from the pressure gauge and from the absolute pressure are different. The author suggested using the exponents calculated from the absolute pressure. The experimental results show that the correlation between the burning rate and the pressure is better suited by the Summerfield formula than the Vieille Law. |
