In order to identify unsteady flow frequency spectrum performance of a n axial compressor and to correlate with its aerodynamic characteristics and sta bility, an experimental study has been made on the unsteady flow frequency spect rum performance of an axial compressor blade row. Test technology and data instr umentation have also been described in this paper. Test results have shown that the test technology is effective and suitable for test of unsteady flow frequenc y spectrum performance of axial compressor.
