    Abstract: A method and system for monitoring a temperature of a gas turbine engine are described. The method comprises obtaining individual sensor readings from functioning temperature sensors of a sensor array, where a number of the functioning temperature sensors is less than a total number of temperature sensors in the sensor array; applying correction factors to the individual sensor readings of the functioning temperature sensors based on deviations of the individual sensor readings from a total average temperature of all the temperature sensors in the array, to obtain corrected individual sensor readings; and determining a corrected total average temperature as a sum of the corrected individual sensor readings divided by the number of functioning temperature sensors.

  • Patent number: 11366034
    Abstract: In a pressure/temperature sensor, a sensor circuit is held by a holding member inside a tube that is fixed to a pipe, and an introduction portion is provided in the holding member at an inner side of the pipe with respect to the sensor circuit. The introduction portion includes a plurality of blades having blade surfaces extending along a protrusion direction of the introduction portion with respect to the sensor circuit. The plurality of blades are arranged radially on a surface perpendicular to the protrusion direction, and angles defined by the blade surfaces of the adjacent blades are all acute angles. Thus, regardless of the angle at which the blade is attached with respect to the flow direction of the measuring medium, an acute-angled portion of any adjacent blades is directed to the flow direction of the measuring medium. Therefore, a pressure loss of the measuring medium can be reduced.

    Abstract: In a gas turbine engine that includes a compressor and a combustor, wherein the combustor includes a primary fuel injector within a fuel nozzle and a secondary fuel injector that is upstream of the fuel nozzle and configured to inject fuel into a flow annulus of the combustor, a method for detecting a flame holding condition about a fuel injector. The method may include the steps of: detecting an upstream pressure upstream of the secondary fuel injector; detecting a downstream pressure downstream of the secondary fuel injector; determining a measured pressure difference between the upstream pressure and the downstream pressure; and comparing the measured pressure difference to an expected pressure difference.

  • Publication number: 20150117490
    Abstract: A temperature sensing device includes a probe unit on a first end and a sensor unit on a second end opposite the first end. The first end is introduced into an environment to be measured, such as an exhaust gas line from a combustion engine, and the second end is positioned in a region outside of the environment such that the sensor unit is at least partially insulated from a temperature of the environment. The probe unit, exposed to the temperature of the environment, achieves a temperature that corresponds to the temperature of the environment. The sensor unit is operable to sense the temperature of the probe unit and generate a corresponding electrical signal usable to determine a sensed temperature of the environment. The temperature of the environment can be determined on a cycle-by-cycle basis, and is usable for implementing advanced combustion strategies such as HCCI and SACI.

  • Patent number: 9004751
    Abstract: A fault diagnosis device conducts a fault diagnosis in a temperature sensor. At starting an internal combustion engine, a thermal equilibrium condition may be established and temperature deviations of temperatures detected by at least two reference temperature sensors from each other may be equal to or less than a predetermined value, with the temperatures detected by the reference temperature sensors being greatly deviated from one detected by a temperature sensor being diagnosed. In this case, if the temperatures detected by the reference temperature sensors do not drop by a predetermined temperature or more from starting the engine until a predetermined time elapses, the fault diagnosis device determines that the temperature sensor being diagnosed is faulty.

  • Patent number: 8992081
    Abstract: A high temperature measurement probe comprises an elongate probe body having a measuring head which in use is located in a hot fluid flow. The probe further comprises a thermocouple extending along the interior of the probe body to terminate at a temperature-sensing thermocouple junction inside the measuring head. The probe body has internal passages for circulation of a coolant fluid therein. The measuring head contains a channel, one end of the channel forming an inlet for receiving hot fluid from the hot fluid flow and another end of the channel forming an outlet for discharging the hot fluid received at the inlet. Between the inlet and the outlet a section of the channel extends along the length direction of the probe body. The thermocouple runs along the section of the channel with the thermocouple junction proximate the upstream end of the section.
