进行了吹吸气静子的设计,并将其与串列转子组合生成一级高负荷扩压级。在吹吸气静子设计过程中研究了吹吸气的位置、稠度等对流动控制的影响。研究结果表明:本文中生成的高负荷静子能达到0.9的扩散因子而不发生分离;吹吸气可以控制从49%轴向弦长处开始的分离,最佳吸气位置在分离点略微靠后的某个位置;最终组合而成的高负荷扩压级能够基本达到原始某高压压气机后两级的做功效果,并有较高的绝热效率,达到设计目标。
The design of the blow-suction stator was carried out and combined with the tandem rotor to generate a first-stage high-load diffuser stage. In the process of blowing the suction stator, the influence of blowing position and consistency on the flow control was studied. The results show that the high-load stators generated in this paper can reach the diffusion coefficient of 0.9 without separation; the blowing-suction can control the separation from the 49% axial chord length, and the best suction position is slightly behind the separation point A certain position; the final combination of high-load diffusion stage can basically achieve the original after a high-pressure compressor two work done effect, and a higher adiabatic efficiency, to achieve the design goals.
