On the marine gas turbine shown in the illustration, the power turbine inlet pressure probes would be mounted nearest the area labeled _______. Illustration GT-0017

Correct Answer: Option C — BB

Power turbine inlet pressure probes are located at the transition duct between the gas generator and the power turbine. In standard gas turbine illustrations, this area (labeled BB) represents the gas path where the high-energy exhaust from the gas generator enters the power turbine section to produce shaft work.
