Glauert Elem. Aerofoil & Airscrew Theory x. 132 The lift force is..inclined backwards at the small angle..and therefore gives a component in the direction of the drag force. This component is called the induced drag, since it is caused by the induced velocity of the trailing vortices. 1931 Flight 1 May 384/2 And how little headway have made such conceptions as induced drag, profile drag and span loading. 1948 Sci. News 7 25 For an aerofoil it is necessary to introduce also the induced drag, i.e. the part of the total resistance which depends entirely on the lift. 1962 F. I. Ordway et al.
