Skin Friction Drag
In the context of aerospace engineering, Skin Friction Drag refers to the resistance experienced by an aircraft or spacecraft as it moves through the air or space. It is a component of parasitic drag and is caused by the friction between the fluid (air or space) and the surface of the vehicle. The friction is due to the viscosity of the fluid and the roughness of the vehicle's surface. The amount of skin friction drag depends on several factors including the shape and size of the vehicle, the smoothness of its surface, and the speed at which it is traveling. Reducing skin friction drag is a key consideration in the design of aircraft and spacecraft, as it can significantly impact fuel efficiency and speed. Techniques to reduce skin friction drag include streamlining the shape of the vehicle, using materials with smooth surfaces, and applying special coatings or treatments to the surface of the vehicle.
