What are the two main sections used to categorize a basic gas turbine engine?

• A. Cold Section And Hot Section
• B. Inlet And Exhaust
• C. Compressor And Turbine
• D. Diffuser And Combustor

Answer: (A)

Two main sections are used: the cold section and the hot section. The cold section handles the air before combustion—things like the inlet, diffuser, and compressor—which compresses and conditions the air while staying relatively cool. The hot section contains the combustion and energy conversion parts—the combustor where fuel and air burn, and the turbine where the resulting high-temperature gas expands to do work. This division reflects how components operate at different temperatures and stages of the process: cold-section components prepare and pressurize the air, hot-section components extract energy from the hot gases. Other terms like inlet, diffuser, compressor, turbine, and combustor are individual parts that fall into these two sections rather than defining a two-part classification on their own.
