AEROELASTIC STABILITY OF AN ARRAY OF FULL-SCALE PANELS FROM THE SATURN S-IVB STAGE AT TRANSONIC MACH NUMBERS

Abstract

Flutter characteristics of a 30-deg segment of the full-scale Saturn S-IVB stage were obtained at Mach numbers from 1.10 to 1.40 for various combinations of axial-compressive loads and panel differential pressures. Flutter was encountered when sufficient axial load was applied to either partially or completely buckle the panels. No structural failure occurred on any of the panels during this test. Static-pressure and boundary-layer surveys were made on a rigid panel at tunnel conditions comparable to those of the flutter phase.
