摘要：本发明涉及航空发动机技术领域，具体为一种修正模拟式综调通道喘振判定系数的方法。该方法引进进口压力信号，进口压力采用空气压力传感器来实现，被测量介质的压力作用在传感器敏感元件上，使其中心点移动，中心点使与其通过连接件刚性连接的差动变压器电枢移动；这时，随着导磁体和差动变压器电枢之间位移变化，改变传感器的输出电压。使用该修正方法后A值的线性关系，A值为静压与总压的比值，当转速大于85％时，A值从随压力逐渐增高从0.3至0.6变化。本发明通过增加进口空气压力信号，可以对A值进行线性修正，更好的判定是否喘振。

The method includes sensing the performance parameters and generating analog sensor outputs, producing digital data by conditioning the analog sensor outputs with at least one hub unit (14) that is mounted sufficiently close to the engine (108) to be subjected to a first temperature in excess of 125°C, receiving the digital data from the hub unit (14) with a collector unit (16) subjected to a second temperature of less than the first temperature, receiving the digital data from the collector unit (16) with a distributor computer unit (18) subjected to a third temperature of less than the second temperature, and processing the digital data with the distributor computer unit (18) to assess the engine performance parameters of the engine (108). The conditioning step is performed with a control circuit board (22) and at least one signal conditioning circuit board (24) within the hub unit (14).

摘要： An engine model calibration system includes a gas turbine engine, a sensor, a nominal engine estimation module for FD&I, and a self-tuning engine estimation module for engine parameter estimation. The nominal engine estimation module includes an open-loop nominal engine model configured to output estimated nominal engine parameters indicative of the one or more engine operating parameters, and selectively updates the open-loop nominal engine model based on one or more identified engine operating conditions. The engine model calibration system can perform calibration of a nominal engine model and a self-tuning engine model as they are used for FD&I and engine parameter estimation. The self-calibrating dynamic model also can separate the long-term tuning parameters and the short-term tuning parameters from one another so that the self-tuning capability for the self-tuning engine model is not compromised or diminished as the engine deteriorates.

摘要： Determining a distance between stationary and moving portions of a turbo machine including generating, by a fixed gap capacitive probe, a first output signal based on a characteristic of a gas in a gas flow path of the turbo machine, wherein the fixed gap capacitive probe is located in the stationary portion and is configured to sense a characteristic of a gas flowing through the gas flow path. Also, a variable gap capacitive probe, located adjacent the fixed gap capacitive probe, is used to generate a second output signal based on a distance between the variable gap capacitive probe and the moving portion, wherein the variable gap probe is configured to capacitively couple to the moving portion of the turbo machine. Afterwards, the value of the second output signal can be adjusted based on the first output signal to produce an adjusted output signal.
