    The invention relates to a system for measuring operating parameters of a rotating machine at extreme temperatures.
    Moving objects in rotating machinery, such as blades in an aircraft engine or in a compressor, may be subjected to stresses during operation in an aggressive environment. Stationary objects of the machines, for example combustion chamber walls, nozzles or shells, can also experience compressive or tensile stresses due to extreme operating conditions, for example in a hot gas path or under minus-temperature conditions. Such compressive or tensile stresses occurring in the objects can damage the machines. Accurately measuring operating parameters of the objects, e.g. Temperature and voltage is required to correct or prevent damage occurring in the machinery. One approach to measuring operating parameters in the machinery is to use wired sensors to be wired between a rotating component and a stationary part of the rotating machine using slip rings. However, an approach that utilizes wiring may be complicated, costly, and unreliable, in part because of the long term high temperature of the machinery, because the electronic properties of the wiring may limit the range of temperatures that a wire-connected sensor is capable of is to work exactly.
    Due to the above-mentioned limitations of wired sensors, operating parameter readings of a machine can only be obtained during a test of the machinery. However, to ensure reliable operation, it is desirable to monitor operating parameters throughout the life of the machinery. Operating parameter measurements obtained in field use can be correlated with control parameters to optimize field operation of the machinery. Changes in the operating parameter measurements observed over time can also be used to evaluate the usage status of the objects or the components of the machinery so that adequate maintenance planning is enabled. Accordingly, there is a need in the art for a harsh environment sensor system which operates accurately over a wide range of temperatures and conditions and which can be used throughout the life of the machinery. It is also desirable for this aggressive environment sensor system to operate wirelessly at high temperatures above 260 ° C (500 ° F) where conventional electronics are not sufficiently reliable.

    Detailed description
    As discussed in detail below, embodiments of the invention relate to a sensor system suitable for aggressive environments and to a method for measuring operating parameters of an object in an aggressive environment. As used herein, the term "aggressive environment" refers to a space in a gas turbine. Temperatures in a space referred to herein as "aggressive environment" in a gas turbine, for example, may range from about 427 ° C to 1371 ° C (800 ° F to 2500 ° F).
    When elements of various embodiments of the present invention are introduced, the indefinite and particular articles "a," "an," "the," etc., are intended to include the presence of more than one element. The terms "comprise", "contain" and "exhibit" are to be understood as inclusive and mean that additional elements may exist that are different from the listed elements. Any examples of operating parameters do not exclude other parameters of the described embodiments.
    Fig. 1 shows a cross-section of a rotating machine 10, for example a turbine engine, and illustrates an embodiment of a suitable for aggressive environment sensor system, which is connected to the rotating machine 10. It should be noted that although the illustrated example relates to a turbine engine application, the invention can be applied in a broader sense to wirelessly measuring operating parameters of components of any rotating machine, including, but not limited to, wind turbines and electric motors. Moreover, the invention may also be applicable to stationary components of the machinery, such as combustion chamber walls, nozzles or shrouds, which are exposed to extreme operating conditions, for example in a hot gas path or under minus temperature conditions. The cross-section of the gas turbine 10 partially illustrates at least two portions of the aggressive environment suitable sensor system disposed on a shell 12 and a blade 16. Although only a single blade 16 is shown, the engine 10 may include a plurality of blades rotating about a shaft 14. The portions of the aggressive environment suitable sensor system illustrated in FIG. 1 include a first power interface element 18 disposed on the shell and a second power interface element 20 disposed on the rotating blade 16 of the gas turbine engine 10. In one embodiment, both power interface elements may be antennas disposed on the engine 10 for detecting energy signals. In a non-limiting example, the energy signals may include electromagnetic waves. The energy signals represent parameters of an aggressive environment in a rotating machine, such as the operating parameters of a moving object of the rotating machine. Non-limiting examples of the power interface elements may include a coil, e.g. an inductor, an antenna construction, metal on an insulator, or a printed circuit board printed on a ceramic substrate.
    In addition, a polling channel 22 connects the first power interface element 18 and the second power interface element 20. Polling channel 22 is a wireless data exchange path for detected signals disposed between the interface elements. The second interface element 20 thus transmits, via the interrogation channel 22 to the first interface element 18, data relating to various operating conditions of the blade, for example high temperatures, pressures or stresses. Non-limiting examples of operating parameters may include temperature, mechanical stresses, pressures, tolerance margins and displacements.
    Fig. 2 shows a block diagram representing a suitable for aggressive environment sensor system 24 having a first energy transmitting / receiving system 26 and a second energy transmitting / receiving system 27, which are connected via a query channel 28. The first energy transmitting / receiving system 26 is preferably located adjacent to or on a stationary part of the rotating machine. In contrast, the second power transmitting / receiving system 27 is preferably mounted on the moving object of a rotating machine. However, the second energy transmitting / receiving system 27 may also be mounted on a stationary component of a machine, with stationary components usually being exposed to extreme conditions, such as a hot gas path or minus temperature conditions. The second power transmitting / receiving system 27 continuously detects a plurality of operating parameters of the object and transmits / receives the data via the polling channel 28. Thus, the second power transmitting / receiving system 27 is configured to be consecutively polled by the first power transmitting / receiving system 26 become. In one embodiment, the query channel 28 is a magnetic channel. In some embodiments, the interrogation channel 28 may be a magnetic coupling, such as a near field, a mutually inductive coupling, or a far-field electrical coupling.
    Fig. 3 illustrates wirelessly connected sensor circuitry of the aggressive environment suitable sensor system 30 according to an embodiment of the present invention. As can be seen, the sensor system 30 includes a first power transmitting / receiving system 31 having a first interface element 32, a processor 36, and a power source 38 in a sensor circuit 34. The first interface element 32, for example an antenna, transmits and receives via a query channel 44 from the second energy transmitting / receiving system 33 energy signals. In one embodiment, the energy source 38 in the circuit 34 may be a voltage source, such as an accumulator or a battery.
    The second energy transmitting / receiving system 33 further includes a second interface element 40 and sensor components 42, which are arranged in a further sensor circuit 41, wherein the sensor circuit 41 may be a passive circuit on the moving object, for example on a Blade of a turbine engine, is arranged. In one embodiment, the sensor components 42 may include a capacitor in conjunction with a dielectric member disposed on the moving object to detect the operating conditions. The moving object may be exposed to high temperatures, pressures, or stresses, thereby causing a change in the dielectric constant of the dielectric member. This changes the capacitance of the capacitor and also causes a change in the impedance of the circuit 41. The modulation of the impedance of the circuit 41 substantially modulates the sense channel 44 between the first power interface element 32 and the second power interface element 40. The modulated sense channel 44 also effects a change in the impedance of the sensor circuit 34 of the first transmit / receive system 31. This modulation of the impedance in the circuit 34 is measured and processed by the processor 36 to determine the operating conditions of the object of the machine.
    It should be noted that embodiments of the invention for performing processing tasks of the invention are not limited to a particular processor. The term "processor" as used herein is intended to mean any machine capable of performing the calculations or computations necessary to carry out the objects of the invention. The term "processor" is intended to mean any machine capable of accepting a structured input and processing the input according to predetermined rules to produce an output. It should also be noted that the phrase "arranged to" as used herein means that the processor is equipped with a combination of hardware and software to accomplish the objects of the invention as would be understood by those skilled in the art.
    Fig. 4 is a block diagram representing a harsh environment sensor system 50 illustrating a functional relationship between various elements of the present invention. The system 50 includes the first power transmitting / receiving system 52 for transmitting and receiving power signals. The first energy transmitting / receiving system 52 may include a combination of a transmitter and a receiver having a common circuit. Each modulation of the impedance of the circuit of the first energy transmitting / receiving system 52 is represented by a modulator 54 (modulating size) sent / received. As a result, the transmitted / received modulator 54 responds to the modulations in the power signals. As can be seen, the system 50 includes a second energy transmit / receive system 56 located in an aggressive environment 58 and located on the object exposed to the aggressive environment 58. The second energy transmit / receive system 56 detects a plurality of operating parameters of the object that is in the aggressive environment 58.
    In one embodiment, the second energy transmitting / receiving system 56 may include a combination of a transmitter and a receiver having a common circuit. The second energy transmitting / receiving system 56 may further include a sensor circuit and a resonant circuit. Each modulation of the impedance of the resonant circuit of the second energy transmit / receive system 56 is represented by a sensing modulator 62 (modulating size). The second power transmitting / receiving system 56 further includes an energy interface element 64. A sensing channel 66 further connects both the sensing modulator 62 and the power interface element 64. The sensing channel 66 is a wireless communication channel that serves to acquire captured data between the sensing modulator 62 and the power interface element 64 to transmit and receive. The interface element 64 may be an antenna in the sensor circuit or in the resonant circuit and provides both the first energy transceiver 52 and the second energy transceiver 56 with a common interface. This allows the transmission of data originating from the object in an aggressive environment to the first power transmitting / receiving system 52.
    Further illustrated in the block diagram of Fig. 4 is a polling channel 60, wherein the polling channel 60 is a wireless data exchange path between the first power transmitting / receiving system 52 and the second power transmitting / receiving system 56. As discussed, the transmitted / received modulator 54 changes in response to the interrogation signal. In a particular embodiment, the transmitted / received modulator 54 changes in response to the capturing modulator 62. The interrogation signal carries data of multiple operating parameters of the object 58 disposed in the aggressive environment. In embodiments where the sense channel 60 includes magnetic coupling, the effective coupling constant (k) of a coupling device between the first energy transmitting / receiving system 54 and the second energy transmitting / receiving system 56 is related to the rate of change of the magnetic field (B) of the interrogation channel 60, for example k ~ d / dt ( B). The query channel 60 is modulated by the detecting modulator 62 with the detecting modulator 62 disposed on the object. In an aggressive environment, operating parameters may cause deformation of the object (eg, the vane may expand) thereby modulating a sensing modulator 62 and causing further modulation of the interrogation channel 60. Thus, the modulation of the interrogation channel (d (B) / dt) is a function of the displacement of the detecting modulator 62. Since the operating parameters of the object are essentially a function of the modulating modulator 62 modulation, the operating parameters can be varied between the first energy transmitting / receiving system 52 and the second energy transmitting / receiving system 56 existing coupling constant (k) determine. This is a passive approach that uses neither active electronics nor pn-junctions.
    Further, a processor 68 connected to the first power transmitting / receiving system 52 processes the interrogation signal. The processor 68 is configured to determine a plurality of operating parameters of the object 58 disposed in the aggressive environment based on the transmitted / received modulator 54. In addition, in one embodiment, the power source 70 connected to the first power transmit / receive system 52 may be a voltage source.
    Fig. 5 illustrates in a block diagram the second energy transmitting / receiving system 80 which is arranged on the object of the rotating machine. As can be seen, a sensor system 82 of the second energy transmit / receive system 80 forms a sensor circuit and, in addition to an interface element 86, includes a sensor 84, such as a dielectric material. In a non-limiting example, the sensor 84 may be a capacitor with the dielectric material disposed on the object. In one embodiment, the secondary energy transmit / receive system 80 may be partially disposed on the moving object, where the sensor 84 may be disposed on the moving object, for example on a blade of an aircraft engine or on a blade of a gas turbine. The remaining features of the second energy transmitting / receiving system 80 may be disposed on the non-moving part of an object. The non-moving part may be outside of an aggressive environment. The second power transmitting / receiving system 80 further includes a resonant circuit, designated by reference numeral 94, having a sensor interface element 90. In one embodiment, the sensor interface element 90 is a capacitor that is connected in parallel in the resonant circuit 94 with an inductance. Any change in the impedance of the resonant circuit 94 is represented by a sensing modulator 92. As a result, the output of the sensor 84 is connected to the sensing modulator 92 via the sensor interface element 90. The channels connecting the multiple sensor elements as shown in FIG. 4 represent multiple paths for the transmission and reception of energy signals in the second energy transmit / receive system 80.
    In one embodiment, the sensor 84 may be selected from a group including a capacitor, an inductor, a nanoscale NEMS device, a microscale NEMS device, and a measurement scale direct write element. The direct write element is a directly imprinted device and includes circuit depositions, wherein the depositions may further include a conductor, a resistor, a capacitor, or an antenna. In some embodiments, interface element 86 may include a material that changes its permeability in response to a temperature, stress, or crystalline deformations that may lead to atomic restructuring.
    Embodiments of interface element 86 may further include a high magnetic permeability material selected to modulate an inductive circuit or a relatively high permittivity material selected to modulate the capacitance of a capacitor circuit. Non-limiting examples of the magnetic permeability material may include nickel (Ni), iron (Fe), cobalt (Co), manganese (Mn), chromium (Cr), copper (Cu), and gold (Au). In some embodiments, the interface element 86 may have a relatively high permittivity to air, allowing the use of a relatively small capacitor. In addition, interface element 86 is an operating parameter responsive material that can be selected for a high Curie point. The present sensor system is capable of producing accurate results at temperatures up to about 649 ° C (1200 ° F). In yet another embodiment, interface element 86 includes a dielectric element disposed on the object in the aggressive environment. The dielectric element may be further selected from an oxide group. Non-limiting examples of the oxide group may include a glass, borosilicate glass, zirconia, alumina, piezoelectric, ferroelectrics, and magnesia. The dielectric constant of the dielectric element varies in direct proportion with operating parameters 88 of the object in an aggressive environment. Non-limiting examples of operating parameters 88 of an aggressive environment of the object include temperature, stress, pressure, tolerance and displacement.
    In a non-limiting example, the sensor 84 may include a capacitor having a high dielectric constant material disposed on a thermal barrier coating of a turbine blade. Non-limiting examples of the high dielectric constant material may include hafnium silicate, zirconium silicate, hafnia, alumina, magnesia, and zirconia. The dielectric constant of the dielectric material may have a direct proportionality to the temperature or stress of the turbine blade. Any change in the dielectric constant directly causes a change in the capacitance of the sensor of the sensor circuit. This induces a modulation of the impedance of the resonant circuit.
    The second power transmitting / receiving system 80 further includes an energy interface element 96. In one embodiment, the power interface element 96 is a transmit / receive antenna for transmitting / receiving power signals via the sense channel 98 to / from the first one (shown in FIG. 3) Energy Transmit / Receive System 52. The second energy transceiver system 80 further includes a compensation component 100. In one embodiment, the compensation component 100 is a modulator that operates only in response to noise parameters 102 and not dependent on the sensor system 82 of FIG second energy transmit / receive system 80 detected operating parameters 88 changes. The noise parameters 102 may include changes in temperature and transmit power. The sensor system 82 may be affected by changes such as power, split, and noise parameters 102. The compensation component 100 is therefore configured to determine an error due to the noise parameters 102. The second power transmitting / receiving system 80 corrects the power signals substantially in correspondence with the error detected by the compensating component 100, and then transmits / receives the power signals. Consequently, the compensation component 100 ensures corrected operating parameter measurements by means of the aggressive environment suitable sensor system.
    In addition, the second energy transmit / receive system 80 includes a power conversion element 104. In one embodiment, this power conversion element 104 converts received energy into a form that may be transmitted and influenced by the sensing modulator 92 and the sensor interface element 90. In yet another embodiment, the second energy transmit / receive system 80 may include an energy transformer. The power transformer may be configured to shift the frequency operating range of the resonant circuit 94, which includes the power interface 96 and the sensor components in the sensor system 82, to a more appropriate range, and the resulting frequency offset, which may be at the first power interface element 32 shown in FIG is amplified.
    Fig. 6 shows an embodiment of a method 200 that serves to measure an operating parameter of an object in an aggressive environment. The method 200 includes, as illustrated at block 202, the step of transmitting / receiving power signals using a first power transmitting / receiving system. In block 204, the method 200 includes the step of modulating a transmitted / received modulator located in the first power transmitting / receiving system via a wireless coupling to a second power transmitting / receiving system, wherein the second power transmitting / receiving Receiving system is at least partially disposed on the object. Further, in block 206, the method 200 includes the step of computing, based on the transmitted / received modulant, by means of a processor, one or more operating parameters of the object disposed in the aggressive environment.
    In some embodiments, in an inductive embodiment of a sensor system suitable for aggressive environments, the modulating element may comprise a high permeability material or, in a capacitive embodiment, a high permittivity material. Some examples of high permeability materials that may be used in embodiments of a sensor suitable for aggressive environments include, but are not limited to, iron alloys, nickel alloys, an iron-nickel alloy, chromium, or other ferromagnetic alloys. Examples of high permittivity materials may include, but are not limited to, oxides, ceramics, alumina, barium silicate, and conventional capacitor ceramic material, such as NPO and X7R or LiNbO3. A suitable material can be selected based on the component arranged in an aggressive environment and on the parameters of the machine to be measured, since different materials can respond magnetically differently to the operating parameters. Embodiments of an aggressive environment sensing system may be used to detect different operating parameters in any machine including rotating components or stationary components, such as, but not limited to, in a compressor or turbine of an aircraft engine a power plant turbine, such as gas or steam turbine, or in a generator.
    Advantageously, the suitable for aggressive environment sensor system allows measuring different operating parameters of the moving object and the stationary objects of a rotating machine. This knowledge facilitates the determination of the overall state of use and the reliability of the machines. In addition, the aggressive environment sensing system effectively forms an integral part of the equipment of machines operating in aggressive environments. As a result, measurements of operating parameter data of machines with improved accuracy, sensitivity and specificity can be made. The use of the aggressive environment sensor system in the equipment of the machines successfully leads to savings in maintenance time and cost.
