本文目的是为了使涡轮机专业学生或涡轮机制造厂设计人员可以在不需要具有较高的气体动力学理论水平和化费大量工作时间的条件下,用简单可靠的方法来建立高效率涡轮机叶栅叶型.在本文中,作者总结有关文献资料提出高数率时栅叶型的要求及其主要参数的选择,同时还介绍常用的两种近似核算叶型质量昀方法和两类叶型成型方法——“应用经验准则”和“弯曲对称叶型中线”的成型方法. The purpose of this paper is to enable turbine students or turbine plant designers to establish a highly efficient turbine blade without the need of having a high theoretical level of gas dynamics and a significant amount of work time In this paper, the author summarizes the relevant literature suggested that the high rate of gate leaf type requirements and the main parameters of choice, but also introduces the commonly used two kinds of approximation leaf mass Yun method and two types of leaf shape method - - “Application Experience Guidelines” and “curved symmetrical leaf centerline” molding method.
