    Abstract: Eddy current non-destructive examination and evaluation of physical properties of a component, such as a generator retaining ring, after experiencing potentially degrading thermal exposure during any stage of manufacture, assembly and service use, is performed to determine whether it is acceptable for service use, requires further modification (e.g., additional heat treatment processing) or whether is permanently unsuitable for service. Eddy current test measurements are correlated with component temperature exposure (e.g., absolute temperature and/or cumulative time-temperature heat absorption) and cumulative alteration of the component physical properties, such as, among others, material yield strength (YS), toughness, and tensile ductility. Using the eddy current test measurements and reference data correlating electrical conductivity with ring material thermal exposure, the component's physical properties are evaluated to determine its serviceability.

    Abstract: Improved methods of detecting thermal exposure are provided herein. The provided methods utilize initially dormant luminescent probes incorporated into a matrix to form a composite. When exposed to heat over a period of time, the luminescent probes are “activated” through a molecular transformation initiated by thermal energy. The activated probes exhibit a luminescent profile based on the extent of thermal exposure, thereby providing an indicator of the thermal exposure experienced by the matrix. When the composite is used to produce a structural component of a vehicle (e.g., an aircraft), the methods provide a convenient, large-area indicator of thermal damage experienced by the structural component.

  • Publication number: 20140153609
    Abstract: The invention relates to the technical field of LDC fabrication and specifically to a high and low temperature test equipment. The high and low temperature test equipment comprises a housing, and further comprises a partition disposed in the interior of the housing. The partition divides the interior of the housing into a plurality of chambers and is provided with a Peltier effect sheet. The Peltier effect sheet is used for, when it is powered-on, cooling at least one of the chambers and meanwhile heating at least one chamber other than the at least one of the chambers. The high and low temperature test equipment may cool and heat at the same time in an efficient, power conserving way and have uniform heating function.

  • Patent number: 8702303
    Abstract: Methods and devices for mounting a sensor are presented herein. A temperature sensor assembly for a capacitor bank is disclosed that includes two opposing substrates, and a plurality of contact temperature sensors attached to each substrate. Each temperature sensor is configured to directly contact a surface of one of the capacitor cans in the capacitor bank and therefrom generate a signal indicative of the temperature of the capacitor can. A biasing member attaches the two substrates together. The biasing member is configured to selectively contract, such that the width of the sensor assembly is less than the gap distance between adjacent sets of tandem capacitor cans and the sensor assembly can insert between the sets of capacitor cans, and expand, such that the width of the sensor assembly is greater than the gap distance and the sensor assembly is tensioned against and thereby secured between the sets of capacitor cans.

  • Patent number: 8696196
    Abstract: A bleed leakage detection system includes an arrangement of thermostats that are capable of detecting the place where the bleed air leakage is occurring (e.g., the failed junction in bleed air duct work). The exemplary illustrative non-limiting implementation provides a bleed leakage detection system with continuous monitoring of thermostat sensor wiring during flight and thermostat self-test function (“Initiated Built In Test”—“IBIT”). The IBIT self-testing can be initiated before the aircraft takes off or optionally, during periodic self testing that may be run during predetermined periods such as overnight when the aircraft is not being flown. By the continuous monitoring the pilot is alerted when a bleed leakage has occurred or when the bleed leakage detection system has failed.

    Abstract: A method for non-destructive testing of open hollow components for tightness supplies a gas under pressure into the component and cools the component in a punctiform manner. Detecting a leak out of the component using a thermographic camera and using a computer connected downstream of the thermographic camera to visualise the leak, follows. The precise location of each leak is thus detected.

  • Publication number: 20140079092
    Abstract: A method and an apparatus for an arrangement including a power semiconductor module with a cooling interface which is connected to a cooling element. The method first measures a first temperature value of the cooling interface, and then changes an operating mode of the power semiconductor module, wherein the operating mode is selected from an active mode and an inactive mode. The method then waits a determined time, measures a second temperature value of the cooling interface, and determines a temperature difference between the first temperature value and the second temperature value. The method then determines a level of a fault risk on the basis of the temperature difference. The apparatus implements the method.

The system includes sensors for sensing the performance parameters and generating analog sensor outputs, at least one hub unit mounted sufficiently close to the apparatus so as to be subjected to a first temperature in excess of 125° C., a collector unit subjected to a second temperature of less than the first temperature, and a distributor computer unit subjected to a third temperature of less than the second temperature. The hub unit has control and signal conditioning circuit boards that operate together to condition the analog sensor outputs of the sensors and produce corresponding digital data. The collector unit transmits the digital data from the hub unit to the distributor computer unit, which processes the digital data to assess the performance parameters of the apparatus.

  • Patent number: 8668382
    Abstract: Disclosed is a method for estimating, within a short time, the life of a cable insulating coating material containing an antioxidant in a suitable concentration based on the rate of decrease of the antioxidant and on the critical concentration of the antioxidant at which oxidative degradation rapidly proceeds. The method tests the coating material to examine its life, the coating material including a base polymer, and an antioxidant having a functional group suppressing an oxidative deteriorative reaction of the base polymer. The method includes performing a thermal degradation test on the coating material; determining the degradation levels and degradation rates of the coating material at two or more time points in the thermal degradation test, based on the ratio of the absorbance of the functional group of the antioxidant to the absorbance of the base polymer; and thereby evaluating the life of the coating material.
