Abstract

This paper presents the results of a study contract funded by the Air Force. The purpose of the
study was to assess the effect of current design criteria and advanced technology on an existing
structure. The structure chosen for the study was the C-141 inner wing box. The design criteria
include the new fatigue and damage tolerance criteria which will probably be required on any new
Air Force aircraft. The advanced technology includes new materials and new structural configurations.
Two alternate box configurations will be presented showing the effects of material properties and
cover configurations on the wing weight. An attempt to predict some trends based on these results is
also presented. The work reported herein was conducted under Contract F33615-72-C-2165 sponsored
jointly by the Air Force Flight Dynamics Laboratory and by the Air Force Materials Laboratory and
published in Technical Report AFFDL-TR-73-51.
