摘要： A method of monitoring an operating parameter of an apparatus. The method comprises taking a measurement of the operating parameter of the apparatus on multiple occasions. The mean and standard deviation of a set of threshold determining values is then determined, the threshold determining values each being dependent on at least one of the operating parameter measurements. Thereafter an event threshold, dependent on the mean and standard deviation of the set of threshold determining values is determined. The operating condition value is monitored, where the operating condition value at any given time is dependent on at least one of the operating parameter measurements. Finally an event signal is generated if the operating condition value is in a regime beyond the event threshold.

摘要： A turbine engine provides a spool supporting a turbine. The spool is arranged in a core nacelle and includes a thrust bearing. A fan is arranged upstream from the core nacelle and is coupled to the spool. A fan nacelle surrounds the fan and core nacelle and provides a bypass flow path that includes a fan nozzle exit area. A flow control device is adapted to effectively change the fan nozzle exit area. A controller is programmed to monitor the thrust bearing and command the flow control device in response to an undesired load on the thrust bearing. Effectively changing the fan nozzle exit area with the flow control device actively manages the bearing thrust load to desired levels.

摘要： A process quantity measurement method with which an engine output is accurately measured in a relatively simple manner. Torque of an engine is measured based on the amount of torsion of the output shaft of the engine, and an engine output is obtained based on the measured torque. On the other hand, an engine output is calculated based on input and output heat quantity, and a difference between the engine output based on the torque and the engine output based on the input and output heat quantity is obtained in advance. When the engine is operated, the previously obtained difference is added to the engine output that is based on the calculated input and output heat quantity to obtain the engine output.

摘要： The invention concerns a method in which oxygen and/or nitrogen is extracted from an air separation unit. The oxygen that is extracted is directed toward a gasifier, and the nitrogen that is extracted is directed toward a gas turbine. At least one parameter related to each gas stream is controlled by acting upon a compressor located within this gas stream's path, and by assigning to that gas stream a parameter, which is related to a variable setpoint value, which represents the load of the gas turbine.

摘要： Four actuators are instructed to move to a condition indicated by a demand line 81. Their actual conditions are indicated by four arrows. The method determines if the range 84 of actual conditions exceeds a threshold value, representing an unacceptable mismatch of actuator positions. This comparison is used to establish further demand instructions. For example, if the range is too great, and the average 82 is below the demand line 81, the devices are instructed to move to the upper extreme position at 88. If the average position 82 is above the demand line 81, the devices are instructed to move to the lower end of the range, at 90. This results in the actuator positions moving together, as they also move toward the demand line 81, reducing risks associated with actuator mismatches.
摘要翻译：指示四个致动器移动到由需求线81指示的状态。他们的实际情况由四个箭头表示。该方法确定实际条件的范围84是否超过阈值，表示执行器位置的不可接受的失配。该比较用于建立进一步的需求指令。例如，如果范围太大，并且平均值82低于要求线81，则指示装置在88移动到上极限位置。如果平均位置82高于需求线81，则指示装置在90°的范围的下端移动。这导致致动器位置一起移动，因为它们也朝向需求线81移动，从而降低风险与执行器不匹配相关。

摘要： A bleed air cooling system for a gas turbine engine includes one or more bleed ports located at one or more axial locations of the gas turbine engine to divert a bleed airflow from a gas turbine engine flowpath, a bleed outlet located at a cooling location of the gas turbine engine and a bleed duct in fluid communication with the bleed port and the configured to convey the bleed airflow from the bleed port to the bleed outlet. One or more safety sensors are configured to sense operational characteristics of the gas turbine engine, and a controller is operably connected to the one or more safety sensors and configured to evaluate the sensed operational characteristics for anomalies in operation of the bleed air cooling system.
