Plots of Coefficients of Lift (C<sub>L</sub>) and Drag (C<sub>D</sub>): Notional representations of data provided by Gustave Eiffel from wind tunnel studies that he performed on cambered plates. The results shown shown are for plates of the same camber, but different aspect ratios, as shown. The locations of the variables at angles of attack for 15° and 30° are shown.
