摘要
本文建立一种基于定制可控扩散叶型的压气机多工况优化设计方法。采用双圆弧中弧线、多段圆弧厚度分布以及椭圆前缘参数化方法,提出一种将叶片气动性能与叶型几何形状参数化结合的定制可控扩散叶型设计方法。基于已有试验进行多工况气动分析的对比验证,提出考虑设计与非设计工况变权重系数的目标函数,在DOE试验设计和Kriging代理模型基础上,利用多岛遗传算法进行优化设计,实现可控扩散叶型在正攻角的损失下降4%。
In this paper, a multi-condition optimization design method of compressor based on customized controllable diffusion profile is established. A customized controllable diffusion profile design method combining aerodynamic performance of blade with profile geometry parameterization is proposed by using double arc middle arc, multi-segment arc thickness distribution and ellipse leading edge parameterization method Based on the existing experiments, the aerodynamic analysis under multiple operating conditions is compared and verified. Based on the DOE experimental design, the approximate proxy model is established, and the objective function considering the variable weight coefficient under design and offdesign conditions is put forward. The multi-island genetic algorithm is used to optimize the design, and the loss of controllable diffusion airfoil at positive angle of attack is reduced by 4%.
