Which components are included in the hot section of a turbine engine?

• A. Combustors, turbine, and exhaust system
• B. Inlet cowlings and supports
• C. Accessory gearbox
• D. Fuel pump

Answer: (A)

The hot section includes the parts that actually handle the high-temperature combustion gases: the combustor where fuel and air burn, the turbine that extracts energy from the hot gases, and the exhaust system that carries the gases away after energy is extracted. These components are designed to withstand extreme heat and sit in the hot gas path. The other items are located in the cold section or outside the hot gas path: inlet cowlings and supports belong to the cold intake area, while the accessory gearbox and the fuel pump are mounted on the engine’s accessory drive and are considered cold-section equipment. Therefore, the components in the hot section are the combustors, turbine, and exhaust system.
