Abstract:
A row of aerofoil members for an axial compressor, the row comprises a circumferentially extending endwall and a plurality of aerofoils extending radially from the endwall. The endwall is profiled to include an acceleration region and a deceleration region in a location that corresponds to a position of peak fluid pressure. The acceleration region is provided upstream of the deceleration region such that fluid flow through the compressor and adjacent the endwall is accelerated and then decelerated so as to reduce the peak fluid pressure.
