    摘要： A brush seal land is disclosed. The brush seal land may comprise a first portion configured to be coupled to a turbine disc of an aircraft engine and a second portion having a contact surface. The brush seal land may comprise a concave annular structure. The second portion may deflect through a clearance area in response to contact with a brush. The second portion may not deflect in response to contact with a brush after the second portion has deflected through a clearance area in response to contact with the brush. The contact surface comprises tungsten carbide. The brush seal land may comprise INCONEL. The brush seal land may be configured to be coupled to an annular member extending from the turbine disc. The brush seal land may reduce abrasion to an annular member extending from the turbine disc by a brush.

    摘要： A gas turbine engine (10) is provided comprising an impeller (114) configured to rotate about an axis (104). A combustor (16) is in fluid communication with the impeller (114). An inflow radial turbine is aft of the impeller (114) and in fluid communication with the combustor (16). The inflow radial turbine includes a rotor with a bore (102) having a flat bore end (112) configured to rotate about the axis (104). A radial turbine is also provided comprising a rotor configured to rotate about an axis (104) and a bore (102) defined by a proximal portion of the rotor. The bore (102) may have a flat bore end (112). A rotor is further provided comprising a disk (101) configured to rotate about an axis (104) and a bore (102) partially through the disk (101) along the axis (104). The bore (102) may comprise a flat section extending radially from the axis (104) and a curved section aft of the flat section.

    摘要： A rotor blade comprises a blade platform and an airfoil. The airfoil comprises a blade tip, a leading edge, and a trailing edge with a stiffening compound lean contour. The blade tip is radially opposite the blade platform, and defines a blade span between the blade itself and the blade platform. The leading and trailing edges extend from the blade platform to the blade tip to define blade chords between the leading edge and the trailing edge. The compound lean contour comprises a positive lean section located at the lean tip, and extending along a lean axis to a lean end. The negative lean section is located radially inward of the positive lean section, and extends along the lean axis to the lean end.
