Abstract (300 words maximum)
The CFM56-7B, a high-bypass turbofan engine developed by CFM International in collaboration with General Electric and Safran Aircraft Engines, represents a cornerstone in modern aviation propulsion, extensively powering aircraft models like the Airbus A320, Boeing 737 NG, and Embraer E-Jet families. The aviation industry is grappling with multifaceted challenges, including those related to environmental sustainability, rising fuel costs, and higher competitiveness. Continuous improvements in aircraft and engine economy are essential to meet these challenges. The objective of the research is to identify opportunities to enhance the performance and efficiency of the CFM56-7B engine, one of the most popular engines in the market. With the intention of modifying the nacelle’s profile to increase pressure inside the inlet, an examination of wind speeds and pressure on the CFM56-7B engine's inlet is presented. The efficiency and performance of the engine can be increased by optimizing the airflow through the nacelle, which can result in less fuel being used and fewer pollutants. The size and shape of the nacelle are modified in this research. The goal is to determine the optimal combination of these parameters that will help maximize the air pressure before the compressor. This will help increase inlet and compressor efficiency and overall engine performance.
