Abstract

The use of slat slots or what is often called slat clearance and flaps is mandatory on aircraft today. Its use is very useful during take off, cruising, and landing. However, these conditions are very different for each wing depending on the configuration and environmental conditions. This study examines the use of wings with the NACA 43018 airfoil during take off. Numerical simulation uses Ansys 19.1 with the turbulent model k-ε Realizable. Free stream flow rate used is 120 m/s with angle of attack (α) = 0°, 2°, 4°, 6°, 8°, 10°,12°,15°, 16°,17°,19°, and 20°. The conditions being compared are plain wing, flap deflection 0°, and 15° with fixed slat clearance during take off conditions. Using a fixed slat clearance, flap deflection δT = 15° produces the highest lift coefficient at angle of attack α = 12° compared to other configurations. However, the drag coefficient produced by the flap deflection δT = 15° is also the highest. With the highest lift coefficient, it is possible to use the maximum take off angle of attack α = 12°.
