在一维设计的压气机叶型基础上,本项目针对其中弧线进行优化,得到了性能更加的三维叶片。在优化叶片中,压气机的工作裕度由55~78kg/s增加至20~88kg/s,设计点处效率增加至90.3%,总增压比下降至2.2,且设计点流量远离失速点和喘振点。
On the basis of one-dimensional compressor blade design, this project optimized the arc of the compressor, and obtained a three-dimensional blade with better performance. In the optimized blade, the compressor operating margin is increased from 55~78kg/s to 20~88kg/s, the efficiency at the design point is increased to 90.3%, the total boost ratio is reduced to 2.2, and the design point flow is far away from the stall point and surge point.
