FIELD: turbine engines.
SUBSTANCE: compressor blade feather (70) for the turbine engine is claimed. Compressor blade feather (70) contains top section (100) containing top wall (106) that extends from input edge (76) of the blade feather to output edge (78) of the blade feather. Top wall (106) forms hollow (110) that continues between input edge (76) and output edge (78). On one of back surface wall (88) or trough surface wall (90), shoulder (104, 105) is provided, which extends between input edge (76) and output edge (78). Transition area (108) narrows from shoulder (104) towards top wall (106). The other of back surface wall (88) or trough surface wall (90) continues towards top wall (106).
EFFECT: rotor blade and/or stator blade for the compressor for the turbine engine is provided, designed to reduce the leakage flow at the top and, consequently, reduce the interaction force between the leakage flow and the main flow, which in turn reduces the overall loss of efficiency.
