What happens to the temperature of the air in the CFM56-7B engine after the high-pressure compressor?

• A. It drops to ambient temperature
• B. It remains constant
• C. It rises to 450 degrees Celsius
• D. It rises to 600 degrees Celsius

Answer: (C)

After the high-pressure compressor in a CFM56-7B engine, the temperature of the air significantly increases due to the energy imparted to it during compression. This increase occurs because the compressor stages effectively compress the air, which results in a rise in pressure and, consequently, temperature as described by the principles of thermodynamics. In a typical operation, the compressed air exiting the high-pressure compressor can reach temperatures around 450 to 600 degrees Celsius. The specific temperature can vary based on various factors like the engine's operating conditions, exact design, and ambient conditions. However, the provided answer indicates a commonly accepted temperature range following compression. Understanding this temperature rise is crucial, as it is a vital parameter for the engine's efficiency and performance. The air must reach specific temperatures to effectively support the combustion process in the combustor that follows, ensuring optimal performance of the engine.
