Introduction Flaps and slats are critical high-lift devices on aircraft wings, essential for safe takeoffs and landings. By modifying wing shape and area, they optimize lift and drag, enabling aircraft to operate efficiently at lower speeds. This article explores their functions, types, operational use, and technological advancements. Illustration showcasing the use of flaps and slats in aircraft, highlighting their role in enhancing performance, safety, and maneuverability. Function and Aerodynamic Principles Lift Enhancement: Flaps (trailing edge) and slats (leading edge) increase wing camber and surface area, boosting lift via Bernoulli's principle. The Coanda effect ensures airflow adheres to the curved wing surface, delaying airflow separation and stall. Drag Management: While increasing lift, flaps also generate drag, necessitating careful deployment to balance speed and control. Types of Flaps and Slats Flaps: Plain Flaps: Simple hinged sections lowering to increase camber. ...
