FURTHER ANALYSIS OF THE RANDOM VIBRATIONS OF THE CARAVELLE TEST SECTION.

Abstract

The vibrations, induced by jet-noise, of a row of skin panels in the side of the rear fuselage of a Caravelle aircraft were analysed. It was found that up to three adjacent panels may couple together in the fundamental stringer-twisting mode in which adjacent panels are out-of-phase. The vibrations of the skin panels in the upper surface of the outboard elevator were also studied and it was found that the ribs act as rigid supports. Any pair of panels between two ribs, however, are vibrationally coupled although the mode-shapes were not satisfactorily determined. (Author)
