1. A system of transient control of a thermal transport bus of a turbomachine comprising:
a turbomachine operable in a plurality of run states;
a thermal transport bus of the turbomachine, wherein the thermal transport bus comprises a working fluid;
a processor;
a temperature sensor that sends a temperature output signal to the processor;
a pressure sensor that sends a pressure output signal to the processor;
wherein the processor directs modulation of thermal transport bus control handles and turbomachine control handles to bring the working fluid into a desired fluid state by:
determining the desired fluid state to bring the working fluid into based on a selected run state signal, the selected run state signal indicating a current one of the plurality of run states in which the turbomachine is operating;
comparing the temperature output signal with a desired temperature range signal, the desired temperature range signal corresponding to the desired fluid state;
comparing the pressure output signal with a desired pressure range signal, the desired pressure range signal corresponding to the desired fluid state;
generating a thermal transport bus control signal and a turbomachine control signal as a function of the comparing of the temperature output signal with the desired temperature range signal and the comparing of the pressure output signal with the desired pressure range signal;
sending the thermal transport bus control signal to the thermal transport bus control handles; and
sending the turbomachine control signal to the turbomachine control handles.
