单词	profile drag
释义	profile drag profile drag n (General Physics) the sum of the surface friction drag and the form drag for a body moving subsonically through a fluid profile drag profile drag [¦prō‚fīl ‚drag] (fluid mechanics) That part of the airfoil drag that results from the skin friction and the shape of the airfoil as indicated by the airfoil profile. profile drag Streamlining reduces profile drag substantial.The combined effect of form drag and skin friction. It is total drag less induced drag. It is a type of parasite drag that increases as the square of speed and is dependent on the shape of the body and its smoothness. See also form drag and skin friction.
