The exhaust section consists of which components?

• A. Exhaust duct, inner cone, struts
• B. Combustion chamber, igniter plugs, fuel nozzles
• C. Turbine blades, rotor disk, rotor shaft
• D. Intake diffuser, compressor, plenum

Answer: (A)

The exhaust section is the part of the engine that guides the spent, high‑energy gases out of the system. It includes the exhaust duct, which channels those gases to the outlet; the inner cone, which shapes the flow as it exits and helps minimize losses; and the struts, which provide structural support for the inner cone and keep the nozzle assembly aligned with the outer casing. The other items listed belong to other sections: the combustion chamber with igniter plugs and fuel nozzles is the combustion section; turbine blades, rotor disk, and rotor shaft are part of the turbine section; and the intake diffuser, compressor, and plenum are part of the intake/compressor section.
