摘要

摘要: 结合附面层抽吸技术提出了一种高负荷对转压气机气动设计方法.在高负荷设计前提下，为避免在转动部件中进行附面层抽吸所带来的诸如强度等问题，利用基于动叶出口轴向速度提升的低反动度压气机气动设计原理，提升动叶出口轴向速度以确保动叶效率，附面层抽吸只在静叶中进行.利用该对转压气机气动设计方法，进行了一对转压气机气动设计验证.三维黏性数值模拟结果表明，在第一列转子与第二列转子叶尖切线速度分别为370m/s与350m/s的前提下，实现了总压比为5.85，效率为88%的两级对转压气机气动设计.

Abstract: An aerodynamic design method combined with boundary layer suction was proposed for counter-rotating compressor. For high-loaded compressor, because of the problems (such as strength problem) caused by boundary layer suction used in the rotating parts, the boundary layer suction was used only in the stator, while the rotor was designed by the low reaction design principle to ensure its efficiency based on the increasing rotor exit axial velocity. A counter-rotating compressor was designed to demonstrate the method above. The three dimensional viscous numerical simulation results show that, two-stage counter-rotating compressor with total pressure ratio of 5.85 and efficiency of 88% is attained at tip tangential speed 370m/s of the first rotor and 350m/s of the second rotor.
