Abstract:

The primary objective of this study was to further demonstrate the applicability of applied load ratios to full-size aircraft components for simulating elevated temperature static tests at room temperature. Plane-strain cross-section procedures are used for analytical definition of the applied load ratios in a similar manner to the original feasibility study performed with the use of simplified box beams. This study includes the experimental and analytical investigation of strength and deformation characteristics of several identical horizontal stabilizers in a room temperature environment as well as in various symmetrical and unsymmetrical steady-state elevated temperature environments. This study also includes the theoretical investigation into the feasibility of using applied load ratios when the mode of failure involves mechanical fasteners in critical splice joint areas. The main conclusion of this study is that although the analytical procedures for the two distinctly different modes of failure are somewhat different, deflection is the major parameter essential to simulation-factor or applied-load-ratio definition.
