    摘要: The present disclosure relates to a propfan engine (100) comprising: one or more rotor stages (110, 120) comprising a plurality of rotors; and an outer wall (130) comprising an outer profile (132), at least a portion of the outer profile defining a substantially circular cross-section, wherein the diameter of the substantially circular cross-section increases in the direction of flow over the outer wall and downstream of a leading edge (112, 122) of the rotors, and the diameter increases at substantially all points defining the circumference of the substantially circular cross-section. The present disclosure further relates to propfan engine (100) comprising: one or more rotor stages (110, 120) comprising a plurality of rotors; and an outer wall (130) comprising an outer profile (132), the outer profile defining a cross-section, wherein the cross-section of the outer profile comprises a maximum diameter (134, 136) at a point upstream of a leading edge (112, 122) of the rotors, the diameter reducing between the maximum diameter and the leading edge of the rotors, and wherein the outer profile comprises a point of inflection (135, 137) between the maximum diameter and the leading edge of the rotors.

    摘要: A tip turbine engine (10) provides an axial compressor (22) having a compressor case (50) from which extend radially inwardly a plurality of outer compressor airfoils (54). The compressor case (50) is directly driven by the rotation of the turbine (32) and fan (28), while at least one gear (77) couples the rotation of the turbine (32) and fan (28) to an axial compressor rotor (46) having a plurality of inner compressor airfoils (52). In this manner, the axial compressor rotor (46) is driven in a direction opposite the direction of the outer compressor airfoils (54), thereby increasing the compression provided by the compressor without increasing the number of airfoils. The outer compressor airfoils (54) are formed on a plurality of outer airfoil assemblies (56) each having an arcuate substratem (58) from which the outer compressor airfoils (54) extend. Each of the outer compressor airfoil assemblies (56) includes more than one axially-spaced stage of outer compressor airfoils (54). For assembly, the outer compressor airfoil assemblies (56) are moved toward the axial compressor rotor (46) and then inserted into the compressor case (50).

    摘要: A rotor has a central shaft (31) having a central longitudinal axis. The rotor has a longitudinal stack (32) of a plurality of disks surrounding the shaft (31). An aft hub (70) couples the stack (32) to the shaft (31). The aft hub (70) has a proximal portion (100) and a distal portion (102). The distal portion (102) tapers at a lower characteristic half angle than does the proximal portion (100).
