SOME FLUTTER EXPERIMENTS AT A MACH NUMBER OF 1.3 ON CANTILEVER WINGS WITH TUBULAR AND CLOSED BODIES AT THE TIPS

Abstract

Flutters tests of 39 cantilever wings with tubular bodies or closed bodies at the tips have been made in a small intermittent-flow supersonic wind tunnel where the testing technique involved changing the structural parameters so that the combinations would flutter at the tunnel Mach number of 1.3. The experimental results are compared with an analysis that uses two-dimensional supersonic air forces on the wing and tube forces derived form a modified slender body theory. The effects of some parameters on the flutter-speed coefficient are determined form the experimental results.
