Pivoting Wing Ride Smoothing/Flutter SAS Analysis,
Abstract
Rigid body studies conducted by Battelle and NASA-Langley have indicated that free floating pivoting wings can significantly reduce turbulence induced vertical accelerations. However, NASA-Langley has shown that a flexible pivoting wing can have an unacceptably low flutter speed. Presented in this document are the results of an analytical follow-on study conducted to determine the feasibility of increasing the flutter speed with an active or passive flutter stability augmentation system (SAS) while retaining significant ride smoothing capability.
