Flutter Prediction in Forward-Swept Wings by Assumed Modes and Strip Theory.

Abstract

The roots are then plotted and the flutter or divergence speeds determined. It was found that flutter speed increased and divergence speed decreased with increasing forward sweep as expected. Also, quasi-steady aerodynamics do not accurately predict flutter and the approximation to unsteady aerodynamics does not accurately predict divergence. It is necessary to combine these two methods in order to obtain a complete analysis of the wing's aeroelastic instabilities.
