What is it about?
This study explores how adding a moving surface to a NACA 2412 airfoil can improve airflow and reduce drag. The system uses a belt with two pulleys to speed up the air over the wing, helping to delay airflow separation, which can reduce efficiency. Unlike past studies that treated the moving surface as a simple flat panel, this research includes real-world details like gaps and pulleys. Tests showed that placing the moving surface at 20% or 40% of the wing’s length, especially near the front, improved efficiency by over 150%, particularly at low angles of attack. These findings could help design better aerodynamic surfaces in the future.
