Abstract
THE phenomenon of the resistance of a fluid to a body moving through it is complicated by the fact that it must depend not only on the density and elasticity of the fluid, but also on its viscous properties and on the nature of the relative motion. Mathematical investigations cannot at present lead to, results that can be usefully applied, say, in aeroplane construction. Recourse must be had to experiment. During the past century many results have been obtained bearing on gunnery and navigation, whilst the great progress in aeronautics has been possible only because of the experiments of pioneers like Lilienthal, Langley, and Eiffel, and the systematic wind-tunnel researches at the National Physical Laboratory and elsewhere.
