摘　　要：搭建了一叶型优化平台,并基于此对一高亚声速叶型进行了多目标优化设计。研究结果表明,应用叶型优化技术后,叶型负荷呈前加载分布且前缘Spike强度减弱,设计以及非设计冲角下的气动损失均大幅度降低,叶型有效工作范围冲角增加。An airfoil optimization platform has been established,and based on this,a high-subsonic airfoil is reconstructed using the multi-points optimization method.As a result,the loading of the optimized airfoil presents fore-loaded distribution and the spike at the blade leading edge is weakened.The aerodynamic loss at design and off-design incidences is reduced and the available operating range is broadened.

关 键 词：高亚声速叶型 优化设计 气动损失
