ABSTRACT:
A ducted fan gas turbine engine is provided with a plurality of sensors which detect the presence of liquid water in air exhausted from the high pressure compressor of the engine into its combustion system. In the event that liquid water is detected, the fuel flow to the combustion system is increased to cause the high pressure compressor to rotate faster and thereby vaporize the liquid water. Such liquid water can be present in the air exhausted from the high pressure compressor when the engine is operating in very heavy rain and can adversely affect normal engine operation.
