摘要： Systems and methods of determining a flame state within a combustor of a turbine engine make use of characteristics of an output pressure of a compressor of the turbine engine and a temperature of exhaust gases of the turbine engine to make a determination. If the first and/or second derivatives of the output pressure of the compressor and the first and/or second derivatives of the exhaust gas temperature of the turbine engine are all positive during at least portions of a predetermined period of time, one can determine that a flame has ignited in the combustor. If those values are negative during at least portions of a predetermined period of time, one can determine that a flame has been extinguished in the combustor.

摘要： Certain embodiments of the invention may include systems, methods, and apparatus for detecting and removing impulse disturbances associated with a sensor signal. According to an example embodiment, a method is provided for detecting and removing impulse disturbances associated with a sensor signal. The method can include receiving signal samples from a sensor, detecting an impulse disturbance when a difference magnitude between a current sample and a previous impulse-free sample is greater than a predetermined threshold value, and outputting the previous impulse-free sample when an impulse disturbance is detected.
