A method and apparatus are described to evaporatively cool air leading to a gas turbine engine by injecting water fog into the inlet air in a controlled manner. A signal is generated representative of the capacity of the inlet air stream to absorb water vapor and used to regulate the amount of fog introduced into the inlet air stream.

A system for evaporative cooling of an air stream leading to the inlet of an internal combustion engine such as a gas turbine engine comprising: fogger means for injecting fog into the air stream; means for generating a control signal representative of the capacity of the airstream to absorb water vapor from fog produced by the fogger means; and means responsive to the control signal for regulating the fogger means so as to cause the injection of fog into the airstream commensurate with its capacity to absorb water vapor, wherein the control signal generating means further comprises: means for generating a first temperature signal representative of the dry bulb temperature of the air stream before being exposed to the fog; means for generating a second temperature signal representative of the wet bulb temperature of the airstream before its exposure to the fog; means responsive to the first and second temperature signals for generating a setpoint signal representative of an achievable temperature of the airstream at said gas turbine inlet.
