Of the air passing through a turbine engine, what percentage is involved with the combustion process?

• A. 20%
• B. 25%
• C. 30%
• D. 35%

Answer: (C)

In a turbine engine, the combustion process occurs in the combustion chamber where fuel mixes with a portion of the compressed air to produce thrust. Typically, this combustion process engages only a fraction of the total air passing through the engine. Approximately 30% of the total air is directed into the combustion chamber, while the remaining air contributes to other functions, such as cooling the engine components and providing necessary airflow for turbine operation. This relatively lower percentage of air utilized in combustion is a result of efficiency designs in modern turbine engines that maximize thrust while minimizing fuel consumption. Understanding this percentage is crucial for comprehending the overall thermodynamic cycle of a turbine engine and how its efficiency is developed. Thus, recognizing that 30% of the incoming air is actively involved in combustion helps in grasping the engine's operational mechanics.
