List the five main sections of a non-modular turbine engine.

• A. Fan section, Compressor section, Combustion section, Turbine section, and Accessory section
• B. Fan section, Combustion section, Core section, Turbine section, and Accessory section
• C. Fan, Compressor, Combustion, Turbine, and Exhaust
• D. Inlet, Core, Burner, Turbine, and Mounting

Answer: (A)

The main idea here is that a traditional non-modular turbine engine is grouped into five major functional blocks: the fan section, the compressor section, the combustion section, the turbine section, and the accessory section. The fan section handles the initial mass flow and pressure rise, the compressor section further increases pressure for efficient combustion, the combustion section adds energy by burning fuel, the turbine section extracts some of that energy to drive the compressor and other stages, and the accessory section houses the gear box and support systems (fuel, lubrication, starting, and other accessories) that keep the engine operating. This arrangement emphasizes both the core flow path and the essential supporting systems. Other options mix in terms like Exhaust or Mounting, or use broader or unrelated labels, which don’t match this standard breakdown of the engine’s major subsystems.
