Development and Flight Test of an Active Flutter Suppression System for the F-4F with Stores. Part 2. Ground Tests and Subcritical Flight Tests.

Abstract

A flutter suppression system was developed and flight tested on an F-4F aircraft. The control law was designed using optimal control theory to minimize the control surface motion and to provide the required stability margins. During the test it was found that the dynamic behavior of the wing-pylon-store changed considerably with excitation amplitude due to free play and preload. The active flutter suppression system worked well and provided an increase in flutter speed.
