11. A thermal management system for a gas turbine engine, comprising:
a thermal transport bus configured to have an intermediary heat exchange fluid flow therethrough, the thermal transport bus comprising:
one or more flow loops;
a first heat exchanger disposed along and in fluid communication with a first flow loop of the one or more flow loops;
a first variable volume device in fluid communication with the first flow loop of the thermal transport bus; and
a second variable volume device in fluid communication with one of the one or more flow loops of the thermal transport bus, wherein the first variable volume device and the second variable volume device are disposed to adjust a pressure of the intermediary heat exchange fluid within the thermal transport bus, and wherein at least one of the first variable volume device and the second variable volume device is configured to adjust a flow volume of the thermal transport bus by 2% to 20% of an initial flow volume of the thermal transport bus.
