设计了一种新型尾缘结构。通过采用双重涡冷双重冲击的方法，最大限度地利用冷却气流，提高整个尾缘的换热能力。在优化圆形截面通道结构过程中，试着通过改变通道横截面积来减少压力损失，通过几种方案比较，认为只扩大出口面积效果最佳。%A new trailing edge was designed .By double impingement and vortex cooling configu-ration ,use cooling fluid farthest to improve the heat transfer of the w hole trailing edge .In the process of optimizing the circle passage configura-tion ,the cross section area of the passage was var-ied to reduce pressure loss .Compared with some cases ,the one only enlarged the area of exit per-formed best .
