介绍了一种平面叶栅反设计方法,假设因压力作用有一流体微元沿槽道中心流线运动,设计参数包括:叶栅进/出口气流角、截面半径、叶型载荷分布和厚度分布等.为完善原设计方法,提出了新的理论,用于获得必要的密度分布曲线;改进了前、后倒圆造型算法,提升了叶栅气动性能;为验证改进后的设计方法,重新设计了德国Aachen涡轮静叶叶栅. A planar cascade anti-design method is introduced. It is assumed that a fluidic micro-element moves along the center of the channel due to pressure. The design parameters include the airflow angle of the inlet / outlet of the cascade, the radius of the section, the load distribution and the thickness distribution of the blade In order to perfect the original design method, a new theory is put forward to obtain the necessary density distribution curve, the front and rear rounding algorithms are improved, and the aerodynamic performance of the cascade is improved. To verify the improved design method, Germany Aachen turbine vane cascade.
