In which section of the LM2500 does combustion occur?

• A. Power Section
• B. Gas Generator Assembly / Combuster
• C. Exhaust Section
• D. Cooling Section

Answer: (B)

Combustion occurs in the Gas Generator Assembly, specifically within the combustor area. This component is critical in a gas turbine as it is where the air, compressed by the compressor section, mixes with fuel and ignites, producing high-temperature gases. These gases then expand and flow into the turbine section, where they drive the turbine blades to produce mechanical power. The Power Section refers to the turbine area but does not encompass where the actual combustion takes place. The Exhaust Section is involved in directing the exhaust gases out of the engine after energy has been extracted, and the Cooling Section is focused on managing temperatures within the system and does not play a role in combustion. Thus, the Gas Generator Assembly is the only part of the LM2500 where the combustion process fundamentally occurs, which is essential for energy generation in the turbine.
