Where is interference drag generated?
Interference drag is a type of aerodynamic drag that arises from the interaction between different aircraft components. When airflow around these components meets, it creates complex flow patterns that increase overall drag. The main areas where interference drag is generated include:
- Wing Root: The wing root is where the wing attaches to the fuselage. The junction between the wing and the fuselage creates complex airflow interactions. The different flow patterns around the fuselage and the wing interfere with each other, leading to turbulence and increased drag.
- Tail Surfaces: The intersections where the horizontal and vertical stabilizers attach to the fuselage also contribute to interference drag. The airflow around these surfaces interacts and causes additional drag.
- Engine Nacelles and Pylons: The junctions where engine nacelles and pylons meet the wing or fuselage can also create significant interference drag. The airflow around the engine nacelles and the wing or fuselage interacts, leading to complex flow patterns and increased drag.
- Landing Gear: When the landing gear is deployed, the intersection of the gear struts with the fuselage or wings can produce interference drag due to the disrupted airflow and the creation of turbulent regions.
