2-2. Surface definition by sections

Wing type sections (airfoils) and body type cross-sections define most aerospace components

Controlled section parameter (key number) variation allows for desired surface quality

Various versions of geometry generator codes, based on original FORTRAN code E88


Sections in planes (here: y = c), calibrated by boundary curves (identified by "key" numbers) in other ordinates (x, z).

Wing-type geometry (keys 20-28)

Body-type geometry (keys 40-48).

Example: vehicle forebody
