A NEW APPROACH TO NUMERICAL FAIRING AND LOFTING

A procedure is set forth for generating a table of offsets describing a fair hull surface without recourse to iterative fairing of the lines. A mathematical representation of the entire surface is built up from a small number of defining functions (either graphically or analytically described) whose shapes are closely related to features of the usual lines drawings. Although the method is fast enough for hand calculation, two ways are suggested for employing machine computation; one resulting in offsets sufficiently precise to eliminate further fairing from the full-scale lofting. Completely worked-out examples of both the graphical and the computer procedures are appended.
