排气参量工程理论计算数学模型

Mathematical Model for Mass Injection Parameter Calculation

排气参量I是底排增程技术中一个十分重要的性能设计参数,但一直采用的是经验估算法,这就使得底排增程技术的应用、研究受到了很大限制。文中首次建立了其工程理论计算数学模型,提出了一种较为简单实用的工程理论算法。理论计算结果与试验结果符合较好,具有较高的参考价值。

Mass injection parameter is a very important parameter in the bleed range extension technology,due to adopt the empirical estimation method and study are significantly limited. The paper setup its engineering calculation mathematical model first time, and put forward a more simple and practical engineering calculation method. The calculation result conforms to experiment. Result well and the reference value is significance.
