The total drag of an aircraft wing consists of two main components: parasite drag and induced drag.

Parasite Drag:

• Parasite drag is caused by the non-lifting parts of the aircraft, such as the fuselage, antennas, and landing gear, as they interact with the airflow. It includes:
• Form Drag: This is related to the shape of the aircraft. Objects with a larger cross-sectional area or non-aerodynamic shapes create more form drag.
• Skin Friction Drag: This is caused by the friction between the air and the surfaces of the aircraft. Smooth surfaces reduce skin friction drag, while rough surfaces increase it.
• Interference Drag: This occurs where different components of the aircraft meet, such as where the wing meets the fuselage. The airflow interactions at these junctions cause additional drag.

Induced Drag:

Induced drag is generated as a consequence of the production of lift. When an aircraft generates lift, it creates wingtip vortices, which induce a downwash behind the wing. This downwash reduces the effective angle of attack of the wing, leading to an increase in drag. Induced drag is primarily dependent on the lift being produced by the wing and is inversely proportional to the square of the aircraft's airspeed. Thus, at lower speeds, induced drag is higher, and at higher speeds, it is reduced.
