Active external store flutter suppression in the YF-17 flutter model

Research output: Contribution to journalArticlepeer-review


A single activated trailing-edge (T.E.) control system (spanning 1% of each wing) is applied to the YF-17 flutter model with the object of suppressing the external store flutter of three different store configurations. The control law is derived by the use of the aerodynamic energy concept and its gains are maintained constant for all three configurations. The results obtained show that the activated T.E. control system leads to very significant increases in the flutter dynamic pressures (QDF) of all three configurations; these increases range between 160-240% increase in QDF. These increases in QDFare maintained over a very wide range of flight altitudes and flight velocities.
