ABSTRACT:
In operation of an engine it is desirable to be able to keep track of engine condition by measuring the values of various engine parameters such as temperatures and pressures and seeing how the relationship between them change. This must be done while the engine is in a steady state condition, generally this requires that the engine be in a cruise condition for some time but this is impractical for military aircraft. It is suggested that each of the sense parameter values be operated on by a trending algorithm which generates a trend estimate which provides a measure of the rate of change of the parameter value. When all of the parameters have trend values are below some pre-set value the engine condition is taken to be at least temporarily steady state condition and parameter values recorded for later analysis.
