摘要/Abstract

摘要： 为了进一步提升压气机级压比，采用附面层抽吸技术，初步建立了一套主要包含S2流面通流计算、吸附式叶型无粘反设计、吸附式叶型带附面层抽吸方案优化、全三维时均流场校核的高负荷吸附式压气机设计体系。研究结果表明:依托该体系仅仅使用1.7%的相对抽吸量完成了一台级压比3.51、等熵效率86.82%、负荷系数超过0.6的吸附式压气机设计，并通过了基于非线性谐波法的三维时均流场校核。由于抽吸基本消除了上游转子叶排的尾迹亏损，级间干涉效应微弱，时均与定常特性线中的峰值效率和压比仅相差0.12%和0.003。

Abstract: In order to further increase the pressure ratio of axial compressor stage，with the method of boundary layer suction，a set of system including S2 through-flow calculation，inviscid inverse design of aspirated airfoil，scheme optimization of boundary layer suction，validation of three-dimension time-averaged flow field calculation was preliminarily established. Research results show that depending on this system，an aspirated compressor which achieves a total pressure ratio of 3.51，an isentropic efficiency of 86.82% and a load factor of more than 0.6 was designed using only 1.7% relative suction mass flow，and validated successfully by three-dimension time-averaged flow field based on the nonlinear harmonic(NLH). As suction basically eliminates wake deficit of upstream rotor，interstage interference is small，and the difference of peak efficiency and total pressure ratio between time-averaged and steady characteristic line is 0.12% and 0.003，respectively.
