Profile drag is the aerodynamic drag that arises from the friction and separation of airflow around the surface of an object in motion. It is caused by the shape, size, and surface conditions of the object, leading to skin friction drag and pressure drag components. Profile drag, also known as form drag. The formula to calculate Profile drag as follows:
where:
- Dskin friction is the skin friction drag in N,
- Dpressure is the Pressure drag in N,
- Dprofile is the Profile drag in N.
