PROBLEM TO BE SOLVED: To provide a compressor rotor that is operable with a sufficient stall range and an acceptable balance of aerodynamic and structural performance.SOLUTION: A compressor apparatus includes a rotor. The rotor includes: a disk mounted for rotation about a centerline axis, an outer periphery of the disk defining a flowpath surface having a non-axisymmetric surface profile; an array of airfoil-shaped axial-flow compressor blades extending radially outward from the flowpath surface, the compressor blades each having a root, a tip, a leading edge and a trailing edge; and an array of airfoil-shaped splitter blades alternating with the compressor blades, the splitter blades each having a root, a tip, a leading edge and a trailing edge. At least one of a chord dimension of the splitter blades at the roots thereof and a span dimension of the splitter blades is less than the corresponding dimension of the compressor blades.SELECTED DRAWING: Figure 1 |
