Parker 91,92 discovers that the nonlinear aerodynamic source of LCO on the Goland wing is
shock motion and the periodic appearance/disappearance of shocks. It is determined that the
combination of strong trailing-edge and lambda shocks which periodically appear/disappear,
limit the energy flow into the structure. This mechanism quenches the growth of the flutter,
resulting in a steady limit-cycle oscillation. Underwing and tip stores are added to the Goland
wing to determine how they affected limit-cycle oscillation. It is found that the aerodynamic
forces on the store transfer additional energy into the structure increasing the amplitude of the
limit-cycle oscillation. However, it is also found that the underwing store interferes with the
airflow on the bottom of the wing, which limits the amplitude of the limit-cycle oscillation.
Parker also attempts to examine an F-16 store-configuration LCO case 93 but is unable to
complete the computation.
Morton 94 is currently developing Kestrel under the DoD CREATE-AV program. Kestrel is
a CFD code based upon the AFRL research code AVUS 95 that is targeted to the need of
simulating multi-disciplinary physics such as fluid-structure interactions, inclusion of propulsion
effects, moving control surfaces, and coupled flight control systems. It will be designed to
address these needs for fixed-wing aircraft in flight regimes ranging from subsonic through
supersonic flight, including maneuvers, multi-aircraft configurations, and operational conditions.
It also utilizes McDaniel’s 96 algebraic deforming mesh algorithm which will allow for LCO type
motions.
