Which of the following is NOT a Hot Section Module Component?

• A. Exhaust Frame
• B. Combustion Liner
• C. Stage 1 Nozzle
• D. Gas Generator Stator

Answer: (A)

Hot section modules are the parts that directly handle the hottest gases produced in the engine, meaning components that live in the combustion and turbine flow path. The combustion liner is the inner wall of the combustor where fuel burns, and the stage 1 nozzle is part of the hot gas path that shapes and directs those hot gases into the turbine. The gas generator stator consists of fixed vanes in the gas generator section that guide the high-temperature flow and withstand extreme temperatures. The exhaust frame, on the other hand, sits in the exhaust/structural area downstream of the turbines and serves as a support/attachment structure rather than a component that participates in the hot gas path. So it is not considered a hot section module component.
