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).

A fan assembly 100 having an outer fan system 130 is disclosed, the fan assembly comprising an outer fan first stage 132 and an outer fan second stage 134 both extending radially outward from an arcuate platform 124.
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).

Die Erfindung betrifft eine Strömungsarbeitsmaschine mit zumindest einem Gehäuse (1) und zumindest einer um eine Maschinenachse (4) drehbaren Rotortrommel (3), wobei in einem zwischen dem Gehäuse (1) und der Rotortrommel (3) gebildeten Ringkanal (2) Statorschaufeln (8) und Rotorschaufeln (7) angeordnet sind, wobei der Ringkanal (2) durch zumindest einen ringförmigen Strömungsteil (11) in einen äußeren Ringkanal (5) und einen inneren Ringkanal (6) unterteilt ist, in denen jeweils Rotorschaufeln (7) und Statorschaufeln (8) angeordnet sind, dadurch gekennzeichnet, dass äußere Rotorschaufeln (7a), welche in dem äußeren Ringkanal (5) angeordnet sind, mit einer unterschiedlichen Drehzahl antreibbar sind, wie innere Rotorschaufeln (7b), welche in dem inneren Ringkanal (6) angeordnet sind.
摘要:
An oil system (118) for a tip turbine engine (10) includes an annular lubricating fluid plenum (136) which sprays lubricating fluid through a multitude of lubricating fluid passages (144, 146, 148) and into the multitude of passages (152,154, 156) located within a gearbox assembly (90) as they revolve thereby. Lubricating fluid is thereby communicated directly into the gearbox assembly (90) and returned to a sump tank (140) through a multitude of drain passages.
摘要:
A turbine engine locates an actuator (55) for the compressor variable guide vanes (54a, b, c) at a location remote from the variable guide vanes. The actuator is connected to the variable guide vanes through a torque rod (56) inside an inlet guide vane. The torque rod rotatably drives an activation ring (57) about the engine centerline. The activation ring is coupled to each of the variable compressor vanes via linkage, such that rotation of the activation ring about the engine centerline causes all of the variable compressor vanes to pivot. With this configuration, a tip turbine engine can be more easily provided with variable compressor vanes for the axial compressor.
