skin friction/surface friction drag — Drag caused by the unevenness in the skin of a body. The layers of air near the surface are retarded, and the speed of the airflow increases as the distance from the skin increases. To reduce the skin friction, the surface should be smoothened to … Aviation dictionary

Drag coefficient — In fluid dynamics, the drag coefficient (commonly denoted as: cd, cx or cw) is a dimensionless quantity that is used to quantify the drag or resistance of an object in a fluid environment such as air or water. It is used in the drag equation,… … Wikipedia
drag — i. That component of aerodynamic forces acting on the wing or the airfoil section, which is parallel and opposite to the relative airflow. The sources of drag are the pressure distribution patterns over the airfoil, called induced drag; the skin… … Aviation dictionary
Drag crisis — In fluid dynamics, drag crisis is a phenomenon in which drag coefficient drops off suddenly as Reynolds number increases. This has been well studied for round bodies like spheres and cylinders. The drag coefficient of a sphere will change rapidly … Wikipedia
