Description and Analysis of a Rocket-Vehicle Experiment on Flutter Involving Wing Deformation and Body Motions

reportActive / Technical Report | Accession Number: ADA377431 | Open PDF

Abstract:

Flight tests and a mathematical analysis were made to demonstrate and confirm a type of subsonic flutter involving rigid-body motions and wing deformations. For the configuration considered, the period of the oscillation was approximately 100 chords per cycle which is well within the range of period found in dynamic-stability work on rigid aircraft with free controls. A mathematical analysis based on two-dimensional incompressible flow provided a conservative prediction of the airspeed at which the low-frequency flutter occurred. It was found that wing bending stiffness is the important parameter for preventing such flutter.
