The experimental study of static pressure distribution on the surfaces of rectangular compressor cascades with different swept blades shows the forward swept cascade weakens the cross pressure gradient in the flow passage

establishes opposite "C" type pressure distribution along the blade height

which helps reduce the accumulation of low energy fluid in the suction corner region

but increases the loss near the midspan.The forward swept-positive curved cascade

compared to the forward swept cascade

further strengthens the capacity of reducing the loss near the endwall and delaying corner stall.
