Abstract: Various aspects of the techniques are directed to a turbine engine comprising a core section, a fan, and an electrical generator. The core section includes a low pressure turbine that drives a low pressure spool that rotates about a longitudinal axis of the turbine engine, a high pressure turbine that drives a high pressure spool, and a compressor rotated by the high pressure spool. The fan is connected to the low pressure spool and rotated by the low pressure spool. Rotation of the fan may provide thrust to a vehicle that includes the turbine engine. The electrical generator is positioned between the fan and the compressor. The electrical generator comprises a rotor concentric with and rotated via the low pressure spool, the rotor configured to rotate about the longitudinal axis, and a stator positioned radially within the rotor and configured to electromagnetically interact with the rotor to generate power.

Abstract: Various aspects of the techniques are directed to a turbine engine comprising a core section, a fan, and an electrical generator. The core section comprises at least one compressor and at least one turbine that both rotate about a longitudinal axis of the turbine engine, wherein the at least one turbine drives at least one spool, and an oil sump positioned to collect oil used to lubricate rotational elements for one or more of the at least one compressor and the at least one turbine. The fan rotated by the at least one spool. The electrical generator integrated into the core section and positioned outside of the oil sump, wherein the electrical generator comprises a rotor rotated via the at least one spool about the longitudinal axis, and a stator configured to electromagnetically interact with the rotor to generate power.

Abstract: A turbine engine includes a core section comprising at least one compressor and at least one turbine that both rotate about a longitudinal axis of the turbine engine; a core vane assembly coupled to the core section, wherein the core vane assembly comprises a plurality of core vanes configured to modify core fluid flow; a fan connected to the core section and configured to be rotated by the at least one turbine, rotation of the fan providing thrust to a vehicle that includes the turbine engine; and an electrical generator integrated into the core vane assembly and positioned in the core section aft of the fan and fore of the at least one compressor, wherein the electrical generator comprises: a rotor mechanically rotated via the fan or a shaft that is rotationally coupled to the fan, wherein the rotor rotates about the longitudinal axis; and a stator.

Abstract: A gearbox rigidly coupled to a static structure; a driven component rigidly coupled to another static structure; a clutch assembly floating between and coupled to the gearbox and driven component. The clutch may have aligned output and input shafts, defining an engagement surface, a bearing, and a magnetic friction plate coupled and rotating with the input shaft. The plate may have a friction-engagement face, and a magnetic flux generator. The magnetic flux generator may be rigidly coupled to a static housing and partially surrounded in the radial direction by a structure configured to reduce leakage of a magnetic flux, by defining a plurality of voids, which direct multiple passes of the magnetic flux through the engagement surface of the output shaft. The magnetic flux generator may create the magnetic flux that creates a magnetic force between the engagement face and the magnetic friction plate that causes them to engage.
