1. An engine control system comprising a non-transitory memory device and a processor, wherein the non-transitory memory device comprises computer-executable instructions, which when executed by the processor, cause the engine control system to perform a method of controlling thermal bias in a turbomachine during a non-started state, the method comprising:
determining a thermal bias-value, wherein the thermal bias-value comprises a difference between an upward temperature-value and a downward temperature-value, the upward temperature-value corresponding to a first one or more temperature measurements of an upward portion of the turbomachine and the downward temperature-value corresponding to a second one or more temperature measurements of a downward portion of the turbomachine;
performing a cooling treatment based at least in part on the thermal bias-value, wherein the cooling treatment comprises at least one of: circulating air through at least a portion of the turbomachine, and rotating a shaft of the turbomachine with a motoring system;
as a result of performing the cooling treatment, deactivating the cooling treatment such that the cooling treatment has an inactive operating state; and
as a result of the cooling treatment having the inactive operating state, setting an engine start status to an enabled operating state.
