An aircraft engine has a combustor supplied by a hydrogen fuel system and is configured to combust hydrogen and generate water vapor. A water vapor collector receives at least part of the water vapor. A condenser is in fluid communication with the water vapor collector to receive and cool in the condenser the at least part of the water vapor and thereby condense at least part of the at least part of the flow of water vapor. A spray nozzle is in fluid communication with the condenser and operable to spray the condensed part of the at least part of the flow of water vapor onto a component of the aircraft engine.

A control system for a gas turbine system includes a virtual filter. The virtual filter is configured to receive a power signal of the gas turbine system having a spray intercooler. The virtual filter is configured to substantially remove sensor noise in the power signal and filter transient power changes of the gas turbine system to provide a filtered power signal. The virtual filter is configured to provide the filtered power signal to a controller of the spray intercooler, wherein the controller is configured to control operation of the spray intercooler based on the filtered power signal.
