Question 31Gas Turbine - 1st Asst/Chief

The correct answer is A) power turbine inlet. Following a shutdown due to an engine fire, the power turbine inlet temperature should be carefully monitored. This is because after a fire, the power turbine inlet temperature may remain elevated even after the engine has been shut down. Monitoring this temperature helps ensure the turbine rotor has cooled sufficiently before attempting any maintenance or inspection, which is critical for safety. The other options are incorrect because the fuel manifold, combustor liner, and compressor discharge are not the critical temperatures that need to be monitored after a shutdown for an engine fire. The power turbine inlet is the key temperature that must be carefully observed in this scenario.
