Which component in the exhaust section collects and delivers gases to the exhaust nozzle?

• A. Exhaust duct
• B. Inner cone
• C. Struts
• D. Turbine rotor disk

Answer: (A)

The exhaust duct is the passage that collects the hot gases after they pass through the turbine and delivers them to the exhaust nozzle. It provides a smooth, direct route for the flow, helping to guide and accelerate the gas into the nozzle where it expands to generate thrust. The inner cone is part of the nozzle structure that shapes the exhaust flow, but it doesn’t collect gases from the turbine. Struts are structural supports and don’t carry the exhaust stream. The turbine rotor disk is a component of the turbine itself, located upstream of the exhaust, not the path that delivers gas to the nozzle.
