跨音轴流压气机设计中落后角的确定
DEVIATION ANGLE DETERMINATION IN TRANSONIC AXIAL FLOW COMPRESSOR DESIGN
-
摘要: 对轴流压气机设计中落后角的选取作了分析, 并对影响落后角的气动和几何因素进行了讨论。通过归纳总结, 提出了一个新的落后角估算公式, 通过对压气机轴流级的验算表明, 该公式能较准确地确定落后角的分布规律。Abstract: The deviation angle determination in transonic axial compressor design is analyzed in detail.In addition,the aerodynamic and geometrical parameters acting on deviation angle distribution are discussed.A new deviation angle calculation formula is provided and applied to redesigning of an axial compressor stage.The results show that the aerodynamic and blade design is quite satisfactory.
