Examination of Operational Dependability Demonstrated by Turbine Reactive Engines

The paper presents course and results of operational examination carried out for engines with particular consideration of land-based tests. It has been suggested that available, already recorded signals from the automatic and control systems can serve as a basis for assessment of the engine operability. The recorded signals can be analyzed in various manners, including the method that is based on the phase trajectory superposed with the Lyapunov function. It has been shown that analysis of signal interrelations presents substantial advantages, where the movement of the phase trajectory vector over the time period is subject to analysis and is related to successive values of the Lyapunov function that is calculated for subsequent moments of time (possibility to analyze both linear and non-linear systems, simultaneous analysis of three signals: operational, environment and feed), therefore the proposed method prevails over other approaches to analysis of signals. The final part of the paper deals with analysis of signals obtained from recorded waveforms from the automation and control systems of the K-15 engine.
