    摘要: A gas turbine engine has, in at least a first mode of operation, a core engine, a fan, and an auxiliary turbine engine coupled as follows. The core engine has, along a core flowpath, at least one compressor section, a combustor, and at least one turbine section. The fan is upstream of the core flowpath and drives air downstream along the core flowpath and along a bypass flowpath. The auxiliary turbine engine has an axial compressor, a fan, a combustor, and an axial turbine. The fan has fan blades and a continuation of the bypass flowpath extends sequentially downstream through the axial compressor and radially outward through passageways in the blades of the fan and a continuation of the core flowpath passes axially through the fan. The combustor is downstream of the fan along the continuation of the bypass flowpath. The axial turbine is downstream of the combustor along the continuation of the bypass flowpath and comprises at least one stage of blades rotating with the fan.

    摘要: A tandem fan-turbine rotor assembly for a tip turbine engine includes a hollow fan blade rotor and a solid fan blade rotor. The hollow fan blade rotor includes a first fan blade rotor hub, hollow fan blades, and an inducer. The solid fan blade rotor includes a second fan blade rotor hub, solid fan blades, an exo-ring, and tip turbine blades. The exo-ring connects the solid fan blades at their maximum outward radial extent. The tip turbine blades are connected to the exo-ring and extend radially outward from the exo-ring. The hollow fan blade rotor and the solid fan blade rotor rigidly attach to each other at the first and second fan blade rotor hubs.

    摘要: Provided is a turbofan engine capable of effectively using the air flowing through the inner diameter side area of a fan that is disposed at the front end side. The turbofan engine in which the fan is disposed at the front end side is equipped with a first low-pressure compressor at the upstream side and on the inner diameter side of the fan. Accordingly, the first low-pressure compressor can be operated by effectively using the air flowing through the rotation center portion of the fan, so that the air can be efficiently used and the output of the engine can be increased.

    摘要: A turbine engine includes an annular combustor having a combustion chamber defined between an annular outer wall and an annular inner wall. A diffuser case substantially encloses the annular outer and inner walls. A fuel nozzle extends through the diffuser case to an outlet that provides fuel to an interior chamber of the combustor. In one embodiment, front portions of the inner and outer walls curve toward one another and overlap to form an annular gap or manifold through which fuel is distributed to the combustion chamber.
