1. A non-transitory computer readable medium comprising instructions that, when executed, cause at least one processor to at least:
obtain condition parameters from sensor devices in a turbine engine;
monitor the condition parameters;
determine when the condition parameters indicate an increase in temperature or a decrease in clearance between a blade tip and a case, the case surrounding at least part of the turbine engine;
in response to determining that the condition parameters indicate an increase in temperature or a decrease in clearance between the blade tip and the case:
transmit a first control signal to adjust a flow rate of a first valve to increase airflow in a first case cooler;
transmit a second control signal to adjust temperature of the airflow through the at least part of the turbine engine; and
transmit a third control signal to trigger a second valve to mix external air in the airflow; and
transmit a fourth control signal to trigger a third valve to route a portion of the airflow to a second case cooler.
