Description

Technical Field

[0001] Aspects of the present disclosure generally relate to electrical energy generation from turbine engines. More specifically, the present disclosure relates to converting mechanical energy from a turbine engine (such as may be used in aircraft and other vehicles) into electrical energy and transferring that energy to an associated vehicle via an electromagnetic field. Background Art

[0002] Various vehicles use various combinations of engines to provide power thrust and maneuvering control to those vehicles. For example, an aircraft may use an engine combined with a turbine to power a jet or propeller. A turbine engine includes several rotating parts to provide power thrust and air / gas compression. A generator connected to the rotating parts of the turbine engine can extract mechanical rotational energy and convert it into electrical energy, which is used to power various onboard systems of the associated vehicle. Due to the wear of various parts of the engine caused by the operating temperature, rotational speed, and airflow within the engine, the physical components used to extract rotational energy from the rotating engine components may be subject to a high replacement rate to avoid introducing reliability issues into other engine components. In addition, due to the location of the energy extraction components in the turbine engine, maintenance and replacement may be difficult to complete or time-consuming. Summary of the invention

DETAILED DESCRIPTION

[0031] The present disclosure provides for extracting and transferring power from rotating components of a turbine engine via electromagnetic (EM) components that are not in physical contact with each other, but extract and convert rotational energy into electrical energy via a series of induced magnetic fields. In some aspects, a permanent magnet attached to a first rotor assembly of the engine rotates relative to a first armature winding on a second rotor assembly of the engine to induce a current in the first armature when two compressors rotate relative to each other while the engine is operating. The induced current in turn powers a high-frequency resonator that generates a second magnetic field having a high frequency to induce a current in a receiving circuit located in a fixed position on a housing or casing of the engine, thereby wirelessly transferring power to an electrical system of a vehicle.

[0032] The electromagnetic power transfer components are arranged in a radially symmetrical manner around the engine and are in contact with a single thrust generating component (e.g., a rotor assembly or a housing). An air gap separates the following components: permanent magnets and armature windings; a resonant transmitter and a resonant receiver. Because no electromagnetic power transfer component is in physical contact with more than one thrust generating component of the engine or another power transfer component connected to a different thrust generating component, the system advantageously suffers less wear and correspondingly reduces the replacement rate of the power transfer components. In addition, the electromagnetic components do not transmit power via wires or shafts arranged in the airflow of the turbine engine, and the electromagnetic components may be relatively light compared to gearboxes and shafts that transmit rotational energy to external generators, thereby providing higher mechanical and fuel efficiency for the engine. In addition, the efficiency of power extraction and transmission via the electromagnetic power transfer components can exceed the efficiency of the mechanical power transfer components, thereby further improving the efficiency of the engine.

[0033] Although the examples provided in this disclosure primarily illustrate the use of the power transfer system in a turbine engine of an aircraft, the power transfer system described in this disclosure may be used in conjunction with automobiles, buses, trains, ships, and various other vehicles.

[0034] Figure 1A and Figure 1B A cross-sectional view of a turbine engine 100 (respectively, turbine engine 100A and turbine engine 100B) including one or more generators 110 is illustrated. The turbine engine 100 includes a casing 120 defining an air inlet 121 at an upstream end, a compression section 122 downstream of the air inlet 121, a combustion section 123 downstream of the compression section 122, a turbine section 124 downstream of the combustion section 123, and an exhaust port 125 at a downstream end. In various aspects, the casing 120 is included inside a nacelle 130 (also referred to as a casing), and a bypass flow chamber 131 is defined between an outer surface of the casing 120 and an inner surface of the nacelle 130. Transmission cable 140 links generator 110 to a power distribution bus 150 or other power transfer mechanism (e.g., a cable connector, a splitter, or a protective device such as a circuit breaker or a bus connection) for a vehicle in which turbine engine 100 is disposed in a bypass flow chamber 131 extending from casing 120 to electrically connect electrical distributor 112 to a power distribution bus (e.g., for a vehicle).

[0035] Figure 1A The turbine engine 100A includes a first coil shaft 160A (generally referred to as a coil shaft or shaft 160 or collectively referred to as a shaft assembly) and a second coil shaft 160B, and Figure 1BThe turbine engine 100B includes a first coil shaft 160A, a second coil shaft 160B and a third coil shaft 160C. Each shaft 160 extends coaxially with the other shafts 160 and rotates at different rates relative to each other during operation due to the injection of high-pressure exhaust gas causing the turbines 180A to 180B (typically the turbines 180) to rotate, and the turbines 180A to 180B in turn drive the associated compressors 170A to 170B or 170A to 170C (typically the compressor 170) at different rates via the associated coil shafts 160. For example, the first coil shaft 160A rotates (due to the force applied by the first turbine 180A) to drive the rotation of the first compressor 170A at a first rotational speed, while the second coil shaft 160B rotates (due to the force applied by the second turbine 180B) to drive the rotation of the second compressor 170B at a second rotational speed. Similarly, in Figure 1B , the third turbine 180C rotates the third coil shaft 160C to drive the rotation of the third compressor 170C at a third rotation speed, wherein the first, second and third rotation speeds are all different from each other.

[0036] The compressors 170 are disposed in the compression section 122 of the housing 120 and may each include a plurality of fan blades arranged in one or more rows. The turbines 180 are disposed in the turbine section 124 of the housing 120 and may each include a plurality of fan blades arranged in one or more rows. Although not illustrated, various bearings or low friction surfaces may be located between the shafts 160 to improve the rotational characteristics of the shafts 160 (e.g., to reduce friction).

[0037] like Figure 1A As shown, the first coil shaft 160A is a low-pressure shaft relative to the high-pressure shaft of the second coil shaft 160B. Therefore, the first compressor 170A is located upstream of the second compressor 170B and rotates at a lower rotational speed than the second compressor 170B during operation of the turbine engine 100. Similarly, the first turbine 180A is located downstream of the second turbine 180B and rotates at a lower rotational speed than the second turbine 180B during operation of the turbine engine 100.

[0038] like Figure 1BAs shown, relative to each other, the first coil shaft 160A is a low-pressure shaft, the second coil shaft 160B is an intermediate-pressure shaft, and the third coil shaft 160C is a high-pressure shaft. Therefore, the first compressor 170A is located upstream of the second compressor 170B, and the second compressor 170B is located upstream of the third compressor 170C, and during operation of the turbine engine 100, each of these compressors operates at a lower rotational speed than the downstream compressor 170. Similarly, the first turbine 180A is located downstream of the second turbine 180B, and the second turbine 180B is located downstream of the third turbine 180C, and during operation of the turbine engine 100, each of these turbines operates at a progressively lower rotational speed than the upstream turbine 180.

[0039] Thus, during operation, there is a first differential rotational speed between the first coil bobbin 160A and the second coil bobbin 160B (and any components attached thereto), and Figure 1B In the embodiment of the present invention, there is a second differential rotational speed between the second coil axis 160B and the third coil axis 160C (and any components attached thereto) (the second differential rotational speed may be the same as or different from the first differential rotational speed).

[0040] The generator 110 includes an electrical extractor 111 attached to the compressor 170 and an electrical distributor 112 attached to the housing 120. The electrical extractor 111 is not physically connected to the electrical distributor 112, but is separated by an empty space (e.g., an "air gap") and is electromagnetically linked by a generated electromagnetic field during operation. The electrical extractor 111 is connected to the compressor 170 and utilizes the different rotational speeds of the compressor 170 attached to different shafts 160 to use the operating rotation of the components of the turbine engine 100 to rotate the components relative to each other. Figure 1A As shown, the electric extractor 111 is located at the interface between the first compressor 170A and the second compressor 170B. Figure 1B As shown, the first electrical extractor 111A is located at the interface between the first compressor 170A and the second compressor 170B, and the second electrical extractor 111B is located at the interface between the second compressor 170B and the third compressor 170C.

[0041] Each electrical extractor 111 is associated with a corresponding electrical distributor 112 (e.g., a first electrical distributor 112A corresponding to the first electrical extractor 111A, a second electrical distributor 112B corresponding to the second electrical extractor 111B) radially attached around a corresponding portion of the casing 120. The electrical distributor 112 includes: a resonant receiver that receives high-frequency power from the electrical extractor 111; and a power conversion unit (PCU) that converts the high-frequency power into a predetermined frequency (e.g., 400 Hz) for consumption and / or storage in a vehicle, and is connected to a power distribution bus 150 via a cable 140. Although not shown, in some aspects using a three-shaft design, the turbine engine 100 may include only one generator 110; omitting one of the first generator 110A or the second generator 110B. In addition, although in Figure 1A and Figure 1B One arrangement of the components of the generator 110 is shown in FIG. 1 , but the components may be arranged in various configurations, such as with respect to FIG. FIG. 2A to FIG. 2B and Figure 3 those discussed.

[0042] FIG. 2A to FIG. 2D Cross-sectional views of components of the generator 110 are illustrated. Figure 2A and Figure 2B A component with a radial magnetic link arrangement is illustrated, and Figure 2C and Figure 2D 1 illustrates a component arranged with an axial magnetic link. As will be understood, as a cross-sectional view, FIG. 2A to FIG. 2D A section of the radially arranged generator 110 is illustrated, and the generator 110 may be arranged at different arc sections of the radial arrangement around the shaft 160 / in the casing 120 of the turbine engine 100 as shown. FIG. 2A to FIG. 2D A picture or Figure 2A Medium to Figure 2D More than one of the figures is constructed as shown.

[0043] The electrical extractor 111 is located at the interface of the two compressors 170A and 170B. For example, the illustrated electrical extractor 111 may be located on the first compressor 170A and the second compressor 170B. In another example, the illustrated electrical extractor 111 may be located on the second compressor 170B and the third compressor 170C. In various aspects, FIG. 2A to FIG. 2D The illustrated components may belong to a single electrical extractor 111 (eg Figure 1A ), or belongs to the primary or secondary electrical extractor 111 (as shown Figure 1B In the aspect including multiple electrical extractors 111, each component can be based on FIG. 2A to FIG. 2D The same figure or a FIG. 2A to FIG. 2D The first figure in the figure and the other one according to FIG. 2A to FIG. 2DAs used herein, when distinguishing components between multiple generators 110, components of one generator 110 may be distinguished by referring to those components as "secondary" components. For example, the first electrical extractor 111A includes a primary permanent magnet 220, and the second electrical extractor 111B includes a secondary permanent magnet 220. In another example, the first electrical extractor 111A is attached to the primary first compressor 170A and the primary second compressor 170B, and the second electrical extractor 111B is attached to the secondary first compressor 170A (which may be a different end of the same compressor 170 as the primary first compressor 170A or the primary second compressor 170B) and the secondary second compressor 170B (which may be a different end of the same shaft 170 as the primary first compressor 170A or the primary second compressor 170B).

[0044] Figure 2A A first component arrangement 200A for an electrical extractor 111 according to aspects of the present disclosure is illustrated. At the interface between the two compressors 170, a first rotor assembly 210A (generally rotor assembly 210) is connected to the lower pressure first compressor 170A, and a second rotor assembly 210B is connected to the higher pressure second compressor 170B. In various aspects, the rotor assembly 210 is connected to one or more blades of the associated compressor 170, to a ring / connection point of the blade that is connected to the associated coil shaft 160, or to the associated coil shaft 160. The rotor assembly 210 positions the various electromagnetic components of the electrical extractor 111 at known distances and orientations relative to each other, the shaft 160, the compressor 170, and the electrical distributor 112.

[0045] exist Figure 2A In the embodiment of the present invention, the first rotor assembly 210A includes a permanent magnet 220 that generates a first magnetic field 215. The permanent magnet 220 radially emits the first magnetic field 215 through an air gap defined as coaxial with the shaft 160 to magnetically link the permanent magnet 220 with the armature winding 230 included in the second rotor assembly 210B. In various aspects, the permanent magnet 220 may include a plurality of magnets arranged circumferentially around the shaft 160 to emit a plurality of first magnetic fields 215.

[0046] The second rotor assembly 210B includes an armature winding 230 and a resonant transmitter 240. The armature winding 230 is arranged concentrically and radially around the permanent magnet 220 or the shaft 160, but is not in physical contact with the permanent magnet 220 or the shaft 160, and the armature winding 230 is positioned within a predetermined field strength of the first magnetic field 215. Therefore, the first magnetic field 215 radially links the permanent magnet 220 and the armature winding 230. In various aspects, when rotated relative to the permanent magnet 220, the armature winding 230 generates a first current (I 1 ) as a multi-phase alternating current, the first current (I1 ) is input to power the resonant transmitter 240 to generate the second magnetic field 225. The second rotor assembly 210B positions the resonant transmitter 240 outside the predetermined field strength of the first magnetic field 215, and therefore, the permanent magnet 220 is positioned outside the predetermined field strength of the second magnetic field 225. The second magnetic field 225 is emitted radially outward from the resonant transmitter 240 to electromagnetically link the resonant transmitter 240 with the resonant receiver 250.

[0047] Figure 2B A second component arrangement 200B for an electrical extractor 111 according to aspects of the present disclosure is illustrated. At the interface between the two compressors 170, a first rotor assembly 210A is connected to a higher pressure second compressor 170B, and a second rotor assembly 210B is connected to a lower pressure second compressor 170A. In various aspects, the rotor assembly 210 is connected to one or more blades of the associated compressor 170, to a ring / connection point of the blade that is connected to an associated coil shaft 160, or to an associated coil shaft 160. The rotor assembly 210 positions the various electromagnetic components of the electrical extractor 111 at known distances and orientations relative to each other, the shaft 160, the compressor 170, and the electrical distributor 112.

[0048] exist Figure 2B In the embodiment of the present invention, the first rotor assembly 210A includes a permanent magnet 220 that generates a first magnetic field 215. The permanent magnet 220 radially emits the first magnetic field 215 through an air gap defined as coaxial with the shaft 160 to magnetically link the permanent magnet 220 with the armature winding 230 included in the second rotor assembly 210B. In various aspects, the permanent magnet 220 may include a plurality of magnets arranged circumferentially around the shaft 160 to emit a plurality of first magnetic fields 215.

[0049] The second rotor assembly 210B includes an armature winding 230 and a resonant transmitter 240. The armature winding 230 is arranged concentrically and radially with the permanent magnet 220 or the shaft 160, but is not in physical contact with the permanent magnet 220 or the shaft 160, and the armature winding 230 is positioned within a predetermined field strength of the first magnetic field 215. Therefore, the first magnetic field 215 links the permanent magnet 220 and the armature winding 230 in the radial direction. In various aspects, when the armature winding 230 is rotated relative to the permanent magnet 220, the first current (I 1 ) as a multi-phase alternating current, the first current (I 1 ) supplies power to the resonant transmitter 240 to generate the second magnetic field 225. The second rotor assembly 210B positions the resonant transmitter 240 outside the predetermined field strength of the first magnetic field 215, and thus, the permanent magnet 220 is positioned outside the predetermined field strength of the second magnetic field 225. The second magnetic field 225 links the resonant transmitter 240 with the resonant receiver 250 in the radial direction.

[0050] Figure 2C A third component arrangement 200C for an electrical extractor 111 according to aspects of the present disclosure is illustrated. At the interface between the two compressors 170, a first rotor assembly 210A is connected to the lower pressure first compressor 170A, and a second rotor assembly 210B is connected to the higher pressure second compressor 170B. In various aspects, the rotor assembly 210 is connected to one or more blades of the associated compressor 170, to a ring / connection point of the blade that is connected to an associated coil shaft 160, or to an associated shaft 160. The rotor assembly 210 positions the various electromagnetic components of the electrical extractor 111 at known distances and orientations relative to each other, the shaft 160, the compressor 170, and the electrical distributor 112.

[0051] exist Figure 2C In the embodiment of the present invention, the first rotor assembly 210A includes a permanent magnet 220 that generates a first magnetic field 215. The permanent magnet 220 emits the first magnetic field 215 through an air gap defined in a plane intersecting the axis of rotation of the shaft 160 to magnetically link the permanent magnet 220 with the armature winding 230 included in the second rotor assembly 210B. Although shown as an air gap defined in a plane orthogonal to the axis of rotation (e.g., for a coaxial magnetic link between the permanent magnet 220 and the armature winding 230), in other aspects, the air gap can be defined at other angles relative to the shaft 160. In various aspects, the permanent magnet 220 can include multiple magnets arranged radially around the shaft 160 to emit multiple first magnetic fields 215.

[0052] The second rotor assembly 210B includes an armature winding 230 and a resonant transmitter 240. The armature winding 230 is radially arranged around the shaft 160, but not in physical contact with the shaft 160, and is arranged in a planetary manner relative to the permanent magnet 220. As used herein, when two objects are described as being "planetary" with respect to each other, it will be understood that the objects rotate around a shared axis of rotation (at the same or different radial distances relative to the axis of rotation), but at different points along the length of the axis of rotation so as to be away from the orbit of the other object (i.e., not in physical contact). The relative position and length of the rotor assembly 210 positions the armature winding 230 within a predetermined field strength of the first magnetic field 215. Therefore, the first magnetic field 215 links the permanent magnet 220 and the armature winding 230 in an axial direction. In various aspects, when rotated relative to the permanent magnet 220, the armature winding 230 generates a first current (I 1 ) as a multi-phase alternating current, the first current (I 1) supplies power to the resonant transmitter 240 to generate the second magnetic field 225. The second rotor assembly 210B positions the resonant transmitter 240 outside the predetermined field strength of the first magnetic field 215, and thus, the permanent magnet 220 is positioned outside the predetermined field strength of the second magnetic field 225. The second magnetic field 225 links the resonant transmitter 240 with the resonant receiver 250 in the radial direction.

At the interface between the two compressors 170, a first rotor assembly 210A is connected to the higher pressure first compressor 170A, and a second rotor assembly 210B is connected to the lower pressure second compressor 170B. In various aspects, the rotor assembly 210 is connected to one or more blades of the associated compressor 170, to a ring / connection point of a blade connected to an associated coil shaft 160, or to an associated coil shaft 160. The rotor assembly 210 positions the various electromagnetic components of the electrical extractor 111 at known distances and orientations relative to each other, the shaft 160, the compressor 170, and the electrical distributor 112.

[0054] exist Figure 2D In the embodiment of the present invention, the first rotor assembly 210A includes a permanent magnet 220 that generates a first magnetic field 215. The permanent magnet 220 emits the first magnetic field 215 through an air gap defined in a plane intersecting the axis of rotation of the shaft 160 to magnetically link the permanent magnet 220 with the armature winding 230 included in the second rotor assembly 210B. Although illustrated as an air gap defined in a plane orthogonal to the axis of rotation (e.g., for a coaxial magnetic link between the permanent magnet 220 and the armature winding 230), in other aspects, the air gap can be defined at other angles relative to the shaft 160. In various aspects, the permanent magnet 220 can include a plurality of magnets radially arranged around the shaft 160 to emit a plurality of first magnetic fields 215.

[0055] The second rotor assembly 210B includes an armature winding 230 and a resonant transmitter 240. The armature winding 230 is radially arranged around the shaft 160, but is not in physical contact with the shaft 160, and is arranged in a planetary manner relative to the permanent magnet 220. The relative position and length of the rotor assembly 210 positions the armature winding 230 within a predetermined field strength of the first magnetic field 215. Therefore, the first magnetic field 215 links the permanent magnet 220 and the armature winding 230 in the axial direction. In various aspects, when rotated relative to the permanent magnet 220, the armature winding 230 generates a first current (I 1 ) as a multi-phase alternating current, the first current (I 1) supplies power to the resonant transmitter 240 to generate the second magnetic field 225. The second rotor assembly 210B positions the resonant transmitter 240 outside the predetermined field strength of the first magnetic field 215, and thus, the permanent magnet 220 is positioned outside the predetermined field strength of the second magnetic field 225. The second magnetic field 225 links the resonant transmitter 240 with the resonant receiver 250 in the radial direction.

[0056] like FIG. 2A to FIG. 2D As shown in the various figures in FIG. 1 , the resonant receiver 250 of the electrical distributor 112 is attached to the inner surface of the housing 120 and is positioned relative to the resonant transmitter 240 to receive at least a predetermined field strength of the second magnetic field 225. The resonant receiver 250 is arranged radially symmetrically around the housing 120 and is configured to receive the second magnetic field 225 to generate a third multi-phase alternating current (I 3 ), the third multi-phase alternating current (I 3 ) is provided to power a control unit 260 (also referred to as a PCU) which regulates the power provided to the vehicle's bus or other electrical distribution system.

[0057] During operation of the turbine engine 100 with the components arranged therein, the rotational force exerted by the turbine causes the compressor 170 and the attached EM components to rotate relative to each other and relative to the stationary casing 120. Due to the difference in the rotational speeds of the higher pressure compressor 170 and the lower pressure compressor 170, the first magnetic field 215 rotates relative to the armature winding 230, and the second magnetic field 225 rotates relative to the (nominally stationary) resonant receiver 250. Thus, electrical energy is extracted from the rotational force of the shaft 160 and transferred wirelessly between the various components via the magnetic fields rather than via mechanical transfer components such as gears.

[0058] For the reader's easy identification and distinction, it has been illustrated FIG. 2A to FIG. 2D 100. However, in various aspects, the manufacturer may vary the relative sizes, shapes, and orientations of the components based on the physical characteristics of the turbine engine 100 in which the components are installed (e.g., length, thickness, circumference, clearance distance, rotational torque and speed, operating temperature), the desired power characteristics of the extracted power (e.g., number of power phases, voltage / current levels), etc. The length of the components along the axis of the shaft 160 is determined by the torque and / or rated power requirements of the vehicle from the turbine engine 100, and within the physical confines of the turbine engine 100, the relative sizes and distances of the various components are adjusted to optimize the torque production and speed from the turbine engine 100 and the power transfer efficiency of the generator 110. Therefore, FIG. 2A to FIG. 2D It is intended to illustrate the concept of operation, not necessarily a specific implementation, which may be modified based on power requirements, thrust requirements, specific fuel consumption of the turbine engine, and material properties of the various components.

[0059] For example, when radial space along the blade length of compressor 170 is more readily available, the manufacturer may Figure 2A or Figure 2B Design permanent magnets 220 and armature windings 230, or when axial space between compressors 170 is more readily available, the manufacturer may choose to design permanent magnets 220 and armature windings 230 according to Figure 2C or Figure 2D Design the permanent magnet 220 and the armature winding 230. Similarly, to optimize the power transfer capability of the electrical extractor 111, the resonant transmitter 240 can be sized and positioned to cover the armature winding 230 and or the permanent magnet 220, so that the resonant transmitter 240 extends over the entire length of the electrical extractor 111, and matches the length and position of the resonant receiver 250 to cover the resonant transmitter 240.

[0060] Figure 3 300 is a circuit diagram of the EM components of the generator 110. The first rotor assembly 210A (including the permanent magnet 220) is arranged to be in magnetic contact, but not physical contact, with the second rotor assembly 210B (including the armature winding 230 and the resonant transmitter 240) via the first electromagnetic field 215. As used herein, magnetic contact describes a state in which the magnetic field generated by the permanent magnet or the electromagnet has at least a predetermined strength between the two components. The armature winding 230 includes a plurality of receiving windings 310A to 310C (generally receiving windings 310), each of which generates one phase of power from the received first magnetic field 215. Although illustrated as providing three-phase current to the resonant transmitter 240 via three corresponding receiving windings 310A to 310C, in other aspects, for example, more or less than three phases may be used by using more or fewer receiving windings.

[0061] like FIG. 2A to FIG. 2D As shown, the first rotor assembly 210A is connected to a compressor 170 of the turbine engine 100, and as shown in FIG. FIG. 2A to FIG. 2D As shown, second rotor assembly 210B is coupled to second compressor 170 of turbine engine 100. Due to differences in the rotational speeds of each compressor 170 when turbine engine 100 is in operation, first rotor assembly 210A rotates at a different speed relative to second rotor assembly 210B.

[0062] Second rotor assembly 210B is arranged to be in magnetic, but not physical, contact with stationary assembly 320 via resonant transmitter 240 and resonant receiver 250. Stationary assembly 320 is disposed on (or through) casing 120 of turbine engine 100 and is therefore stationary relative to rotary compressor 170 and the EM components connected thereto. Stationary assembly 320 includes resonant receiver 250 and power control unit 260, which physically connects stationary assembly 320 to the vehicle's electrical bus or other power distribution system. Figure 5 The resonant transmitter 240 and the resonant receiver 250 discussed in more detail respectively generate and receive the second magnetic field 225 as a high frequency magnetic field at a predetermined resonant frequency to produce a power output to the power control unit 260 and the vehicle.

[0063] Figure 4 4 is a circuit diagram 400 showing in detail a three-phase example of a resonant transmitter 240 and a resonant receiver 250 according to aspects of the present disclosure. The armature winding 230 includes a plurality of receiving windings 310A to 310C, each of which generates one phase (e.g., I ) of power due to the interaction of the armature winding with the received first magnetic field 215. 1Φ1 ,I 1Φ2 ,I 1Φ3 ). In aspects where more or less than three phases of power are used, a different corresponding number of receiving windings 310 are used. Power is transmitted from the receiving winding 310 to a high frequency three-phase converter 410 (e.g., one or more insulated gate bipolar transistors (IGBTs), metal oxide semiconductor field effect transistors (MOSFETs), or other controlled switching devices) to increase the frequency of the power to generate a second magnetic field 225 having a predetermined frequency. The predetermined frequency is greater than the difference between the rotational speeds of the compressor 170 to which the resonant transmitter 240 and other components of the electrical extractor 111 are connected, and is tuned for power transfer efficiency over the air gap between the resonant transmitter 240 and the resonant receiver 250. Transmitter capacitors 420A to 420C (typically transmitter capacitors 420) are provided at respective output terminals of the high frequency converter 410, and each of the transmitter capacitors 420A to 420C is connected in series with the phase inductors 430A to 430C (typically phase windings 430) to form an LC resonant circuit to generate a second magnetic field 225 of a predetermined resonant frequency.

[0064] Each phase winding 430 receives the high frequency power of one phase and generates one phase of the second magnetic field 225. Each corresponding receiver winding of the corresponding receiver windings 440A to 440C (generally the receiver winding 440) of the resonant receiver 250 is connected in series with the corresponding receiver capacitors 450A to 450C (generally the receiver capacitor 450) and forms an LC resonant receiving circuit, which receives the second magnetic field 225 of a predetermined resonant frequency to generate a corresponding phase (for example, I 2Φ1 ,I 2Φ2 ,I 2Φ3 ). Each receiver resonant circuit, inductor or winding 440, and capacitor 450 are connected to a power control unit 260. The power control unit 260 may convert power from AC to DC (or convert DC to AC), increase or decrease the number of phases of power, establish or disconnect an electrical connection to a bus, increase or decrease the voltage of power, increase or decrease the frequency of power, etc., to condition the power for consumption or storage by the vehicle.

[0065] Despite Figure 4 2 is shown as a series arranged LC (inductive and capacitive) circuit, but in other aspects, the circuits of the resonant transmitter 240 and the resonant receiver 250 may include other arrangements of RLC (resistive, inductive and capacitive) elements that allow for a resonant magnetic link between the resonant transmitter 240 and the resonant receiver 250 when the resonant transmitter 240 is powered. Other examples include parallel LC circuits, RLC circuits, actively tuned resonant circuits, etc.

[0066] Figure 5 is a flow chart of a method 500 for construction of generator 110 according to aspects of the present disclosure. Method 500 may be performed during initial assembly of turbine engine 100, during modification or repair of turbine engine 100, or as a pre-assembly work of components of turbine engine 100.

[0067] The method 500 begins with frame 510, where the manufacturer attaches the permanent magnet 220 to the first compressor shaft. In various aspects, the first compressor shaft can be the shaft 160 associated with the lower pressure compressor 170 or the higher pressure compressor 170 at the interface area of ​​the two compressors 170, and the permanent magnet 210 is attached directly or via the first rotor assembly 210A. In various aspects, frame 510 can be repeated to allow the manufacturer to attach the secondary permanent magnet 220 to the secondary first compressor shaft (e.g., at a different location on the shaft 160 within the primary generator 110) for use in the secondary generator 110 in the three-shaft turbine engine 100.

[0068] At box 520, the manufacturer attaches the second rotor assembly 210B including the armature-emitter assembly to the second compressor shaft. For example, when attaching the permanent magnets 220 to the shaft 160 of the higher pressure compressor 170, the manufacturer attaches the second rotor assembly 210B to the shaft 160 associated with the lower pressure compressor 170, but when attaching the permanent magnets 220 to the shaft 160 associated with the lower pressure compressor 170, the second rotor assembly 210B is attached to the shaft 160 associated with the higher pressure compressor 170. The interface area between the first compressor 170 and the second compressor 170 defines an area without fans or blades of the corresponding compressor 170. In multiple aspects, box 520 can be repeated to allow the manufacturer to attach the secondary second rotor assembly 210B to the secondary second compressor shaft (e.g., the shaft 160 associated with the third compressor 170C) for use in the secondary generator 110 in the three-shaft turbine engine 100.

[0069] The second rotor assembly 210B includes an armature winding 230 and a resonant transmitter 240 and a spacer. The spacer arranges the armature winding 230 and the resonant transmitter 240 to position the armature winding 230 in the first magnetic field 215 and separate the first magnetic field 215 from the second magnetic field 225 when the compressor 170 rotates relative to each other during operation of the turbine engine 100. The spacer also positions the resonant transmitter 240 at a set position to interface with and magnetically couple with the resonant receiver 250 when the turbine engine 100 is in operation.

[0070] At block 530, the manufacturer attaches a resonant receiver 250 to the inner surface of the outer casing 120 of the turbine engine 100 relative to the interface area between the two compressors 170 and where the second magnetic field 225 is generated during operation of the turbine engine 100. In various aspects using a three-axis design, block 530 may be repeated to allow the manufacturer to attach a secondary resonant receiver 250 to a secondary location on the inner surface of the outer casing 120 corresponding to the interface area between the two compressors 170 used by the secondary generator 110 and where the secondary second magnetic field 225 is generated during operation of the turbine engine 100. The method 500 may then end.

[0071] Figure 6 is a flow chart of a method 600 for wirelessly extracting electrical energy from a turbine engine 100 according to aspects of the present disclosure. As will be appreciated, in a three-shaft turbine engine 100, the method 600 may be performed twice in parallel - extracting electrical power from the differential rotation of the primary generator 110 and the secondary generator 110 at the interface between different pairs of compressors 170.

[0072] The method 600 begins at box 610, where an operator of the turbine engine 100 causes a permanent magnet 220 attached to a first compressor 170A of the turbine engine 100 to rotate relative to a second compressor 170B of the turbine engine 100. The operator may cause the relative rotation by engaging the turbine engine 100 to generate thrust for a vehicle, inducing rotational energy on the compressor 170 through the combustion of fuel in a combustion chamber, and exhausting exhaust through a turbine area, thereby causing the turbine 180 to rotate the corresponding shaft 160 and thereby rotating the compressor 170. The permanent magnet 220, which may be part of an array of permanent magnets 220 connected to the first compressor 170A and radially arranged around the shaft 160, emits a first magnetic field 215. When rotated, the first magnetic field 215 induces a first current in the armature winding 230 as a multi-phase alternating current (e.g., I lΦ1-3 ), the armature winding 230 is connected to the second compressor 170B and is also radially arranged around the shaft 160. In various aspects, the armature winding 230 is arranged coaxially with the permanent magnet 220, arranged in a planetary manner with the permanent magnet 220, or arranged alternately coaxially and planetary manner with the permanent magnet 220 around the shaft 160. In other words, the air gap between the permanent magnet 220 and the armature winding 230 (through which the first magnetic field 215 propagates) can be coaxial with the shaft 160, defined in a plane intersecting the shaft 160, or vary between coaxial or intersecting planes at different locations around the shaft 160.

[0073] In various aspects, the "first" compressor 170A may refer to the first of the high-pressure compressor or the low-pressure compressor in the two-shaft turbine engine 100, and the "second" compressor 170B may refer to the other compressor. Similarly, in a three-shaft turbine engine 100, the "first" compressor 170A may refer to the high-pressure compressor or the low-pressure compressor, in which case the "second" compressor 170B refers to the medium-pressure compressor, or the "first" compressor 170A may refer to the medium-pressure compressor, in which case the "second" compressor 170B may refer to the high-pressure compressor or the low-pressure compressor. As will be understood, the designations of "high", "medium", and "low" pressure are used to refer to different components within the turbine engine 100 based on the relative operating pressures between the different components of the turbine engine 100. Therefore, in a given pair of rotors, one rotor should be understood as the higher-pressure rotor, and the other rotor should be understood as the lower-pressure rotor.

[0074] At block 620, the first current (I 1) powers an electromagnet (e.g., resonant transmitter 240) to generate a second magnetic field 225 having a predetermined frequency or higher than a predetermined frequency. In various aspects, the predetermined frequency is tuned to characteristics of turbine engine 100 (including, but not limited to, the distance between resonant transmitter 240 and resonant receiver 250, the relative position of second magnetic field 225 in space to first magnetic field 215 in generator 110, the relative position of primary generator 110 to secondary generator 110, the rotation speed of compressor 170, etc.). In various aspects, the predetermined frequency is set high (e.g., at least 10 kHz) to reduce losses when power is wirelessly transferred to resonant receiver 250 via resonant transmitter 240.

[0075] At block 630, the resonant receiver 250 disposed on the inner surface of the housing 120 converts the radiated electromagnetic field power (from the rotating second magnetic field 225) into an electrical power output. In various aspects, the electrical power output is a fourth current (I 4 ), which is provided as a multi-phase alternating current (AC) electrical power output, but in other aspects, the electrical output can be single-phase and / or direct current (DC), depending on the power consumption characteristics of the vehicle.

[0076] At block 640, the resonant receiver 250 delivers the power to the electrical bus for use and / or storage by the vehicle. In various aspects, the resonant receiver 250 delivers the power output to the bus via the power control unit 260, which can condition the power, convert the power from AC to DC (or convert DC to AC), reduce or increase the number of phases of the power, make or break an electrical connection to the bus, increase or decrease the voltage of the power, increase or decrease the frequency of the power, etc.

[0077] The method 600 may continue as long as the first compressor and the second compressor 170 rotate relative to each other.
