Abstract
A gas turbine engine ( ) wherein combustion conditions are controlled as a function of the humidity of the ambient air ( ) in order to ensure stable, emission-compliant performance over a range of ambient conditions. The pilot fuel fraction supplied to a dual mode combustor ( ) may be controlled to be responsive to the relative humidity or the specific humidity of the ambient air. Humidity may be measured directly or it may be calculated as a function of other temperature and pressure measurements. A fuel system ( ) is controlled by a controller ( ) having as inputs the signals from one or more of a relative humidity sensor ( ), a barometric pressure sensor ( ), a wet bulb temperature sensor ( ) and a dry bulb temperature sensor ( ).
