Techniques are derived for approximating maximum cross section areas, wetted areas, and other aerodynamic parameters prior to &quot;sizing&quot; the aircraft through conventional design techniques. A separate dissertation is included to show that structural percentage of gross weight varies predictably with density.</style></abstract><work-type><style face="normal" font="default" size="100%">11.0.
