Abstract:

A preliminary design study was conducted to define and evaluate new structural concepts which will provide increased reliability, integrity, and efficiency and thus reduce the risk of failure of the wing carrythrough structure in an advanced strategic bomber. This study was accomplished by integrating and exploiting newly developed materials, fracture mechanics, analysis methods, nondestructive inspection, and available information from other research and development programs. A continuous iteration was conducted on candidate designs. Finite element, stress, fatigue, and fracture analyses were conducted to include design refinements and provide realistic estimates of weight and integrity. Manufacturing and quality control requirements were reviewed to estimate production feasibility and cost. A merit rating system was used to evaluate proposed designs. This study identified six structural configurations which are significantly lighter and less costly than the Baseline design while satisfying structural integrity requirements. The three most promising configurations were recommended for further development. A program to continue the concept development through detail design fabrication and demonstration testing has been defined. Author
