Design, Fabrication, Testing and Analysis of Torsion Free Wing Trend Flutter Models

Abstract

Trend type aluminum plate flutter models of a Torsion Free Wing (or free floating wing) were designed, built and wind tunnel tested. Types of models tested included cantilever, torsion free wing with a forward trim surface and torsion free wing with an aft trim surface. Several flutter points were obtained in the wind tunnel. The models were also vibration tested and static deflection tested to measure influence coefficients. These measured data were then used in flutter and divergence analyses. The correlation between analysis results and wind tunnel results is good for some cases and fair or poor for others. Reasons for lack of correlation in some cases are given.
