In this paper, results of a study of structural layouts of post-WWII aircraft are
presented. This study was undertaken to provide the background information necessary to
determine typical layouts, design practices, and industry trends in aircraft structural design.
Design decisions are often predicated not on performance-related criteria, but rather on
such factors as manufacturability, maintenance access, and of course cost. For this reason, a
thorough understanding of current “best practices” in the industry is required as an input
for the design optimization process. To determine these best practices and industry trends, a
large number of aircraft structural “cutaway” illustrations were analyzed for five different
aircraft categories (commercial transport jets, business jets, combat jet aircraft, single-
engine propeller aircraft, and twin-engine propeller aircraft). Several aspects of wing design
and fuselage design characteristics are presented here for mercial transport and
combat aircraft categories. A great deal monality was observed for transport
structure designs over a range of eras and manufacturers. A
