Aircraft and Naval Technique: A Study of the Relationship Existing Between the Two in Design and Operation

PHYSICISTS are well acquainted with the relationship which exists between naval and the aeronautical problems. Although the specific gravity of water is a thousand times greater than that of air, the similitude in their flow goes beyond the limits of mathematical analysis; but experiments in water, which have the advantage of being easy of application, although requiring certain precautions, have yielded a number of conclusions that have proved useful in the case of sections and other component parts of aeroplanes.
