Gas turbine engines often operate in such meteorological circumstances, when the air entered the intake of the engine has significant amount of water content. The ingestion of water by gas turbine engines changes the process which takes places in the compressor, turbine, combustion chamber, turbine and nozzle. In unfavourable conditions an engine flameout is also possible. In this paper, the effect of water ingestion on the engine operation is analysed. It explores the physical content of the processes occurred in the engine and deals with the mathematical modelling of them. The method of examination is based on the application of the mathematical model of the engine. Finally the results of investigations are demonstrated.
