Fatigue and Damage Tolerance Effects on Preliminary Design Wing Weights}, booktitle = {34th Annual Conference, Seattle, Washington, May 5-7}, year = {1975}, month = {5/5/75}, pages = {20}, publisher = {Society of Allied Weight Engineers, Inc.}, organization = {Society of Allied Weight Engineers, Inc.}, type = {2. AIRCRAFT LOADING - PAYLOAD}, address = {Seattle, Washington}, 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. }, keywords = {02.
