摘　　要：Detailed experimental investigation has been performed with negative curved blade compressor cascade. The cascade exit flow field, the static pressure on blade surfaces and endwalls were surveyed at five incidences, and the flow visualization was carried out at zero incidence.The experimental results show that using negative curved blade the cascade aerodynamic characteristics can be improved, the secondary loss reduced, the field of static pressure reorganized and good flow field structure established.Detailed experimental investigation has been performed with negative curved blade compressor cascade.
