Abstract

Examination in Article I of the nature of the force arising on a body in steady motion through the atmosphere, showed it to depend upon the shape and size of the body, the density and viscosity of the air, and the relative velocity. No other factor enters which cannot be traced to these variables until, at velocities approaching that of sound, compressibility makes itself felt. Mathematical difficulties compel us to leave the question of shape to the laboratory, where smallscale models may be suspended in an artificial wind, and aerodynamical details determined by practical means. The design of aircraft from experimental data, with regard to shape, may involve, however, large changes in the other variables, and it is essential to investigate at the outset what means and justification exist for the transition.
