英文摘要	Experimental investigations are performed in a three-stage low-speed axial compressor with variable inlet guide vanes (IGV) and adjustable stators. The characteristics of the compressor, especially the efficiency and stall margin, are analyzed in design and off-design operation conditions by adjusting stagger angles of IGV and stators as well as changing the rotational speed. The experimental results show that the off-design performance of the multistage axial compressor is improved by restaggering of IGV and stators related to rotational speed. Considering the background of engineering applications, digital signal processing (DSP) technique is used to realize online adjustment of stagger angles according to the corresponding relations between incidence angles of rotor and rotational speed.
