摘要：The compressor has a shroud (36) with upper and lower surface ramps (38, 40)joined upstream of a leading edge (28) of a blade to form a projection (42). A profile ofthe projection is twisted about a longitudinal axis of the shroud to force gas streamflowing in flow passages to flow around a blade root (16). The ramp (40) has a profilebetween the edge and a trailing edge (30) of the blade, and inclined relative to an outersurface of the shroud to deflect the gas stream flowing in the corresponding passagefrom an upper surface side of the blade to a lower surface side of an adjacent blade.
