Advanced Metallic Structures: Air Superiority Fighter Wing Design for Improved Cost, Weight and Integrity. Volume IV. Baseline Damage Tolerance Evaluation.

Abstract

The basic objective of this study was to provide an updated analysis of the F-111F baseline wing box reflecting the latest proposed Air Force version of damage tolerance criteria. In addition, sensitivity and trade studies were made on the baseline. The effect on allowable stress and service life due to variation in KIc, da/dN, initial damage assumptions, and service usage were determined. NDI experience, thermal and chemical environment, and the impact of a fracture control plan were studied. Baseline data on inspection experience was compiled. The impact on stress levels and life of varying the residual strength load requirement was determined.
