1. A system comprising:
a main supply line;
a thermal recirculation pump in fluid communication with the main supply line for supplying the thermal recirculation pump and with a thermal recirculation line for providing fluid at an elevated pressure to the thermal recirculation line relative to the main supply line;
a thermal recirculation control connected in fluid communication to be supplied from the thermal recirculation line;
wherein a cooler system of one or more coolers is connected in fluid communication with a cooler supply line of the thermal recirculation control;
a boost pump connected in fluid communication between a supply and the main supply line upstream of an inlet line for supplying the thermal recirculation pump and one or more gas generator systems supplied by the main supply line;
an actuation system in fluid communication to be supplied from the main supply line at a point upstream from the thermal recirculation pump; and
a wash screen in the main supply line, configured to filter flow entering the actuation system through the wash screen, and configured to wash the wash screen with flow through the main supply line.
