Abstract

This paper explores the aerodynamic implications of flap angle adjustments on aircraft performance, with a focus on optimizing lift and drag characteristics during critical flight phases such as takeoff and landing. Trailing-edge flaps, including plain, slotted, Fowler, and Gurney flaps, are examined for their roles in modifying wing geometry to enhance lift or manage drag. The study investigates how different flap angles influence airflow, pressure distribution, and boundary layer behavior, using both computational fluid dynamics (CFD) simulations and real-world applications in commercial and military aviation. It highlights specific aircraft, such as the Airbus A320, Boeing 737, and C-17 Globemaster III, showcasing advanced flap systems tailored for efficiency and stability. Furthermore, the study discusses the operational challenges in material durability, maintenance, and certification, as well as emerging trends such as morphing flaps and AI-driven adaptive control. Overall, the research demonstrates how intelligent flap angle management contributes to safer, more efficient, and environmentally sustainable flight operations.
