NOVA-2S Correlation with KC-135A Fuselage Shock Tube Test Results

Abstract

Correlation of the experimental results from KC-135A fuselage tests in the Sandia shock tube with analytical results generated through the NOVA-2LTS structural response code were performed in this effort. It was found that skin buckling between stringers was a very important factor in the overall response of the frames. NOVA-2LTS had to be modified to handle skin buckling in an approximate manner without generating a prohibitive large solution model. Comparisons are made between the experimental results and NOVA-2LTS analytical strain results for the unpressurized and pressurized KC-135A fuselage. Overall the strain response results for the central frame correlated well considering the uncertainities involved in defining structurally an actual large stiffened aircraft section.
