Studies in Non-Linear Unsteady Aerodynamics
1986Abstract : A research program in non-linear unsteady aerodynamics is summarized. New computational and theoretical methods ideally suited for viscous unsteady aerodynamic problems are described. Improved understanding of important physical processes involved in non-linear unsteady aerodynamics are discussed.

Unsteady aerodynamics: retrospect and prospect
The Aeronautical Journal, 1999AbstractThis paper reviews some current problems in unsteady aerodynamics and discusses some future challenges. The emphasis is on problems associated with separated flows, such as buffeting and limit cycle oscillations. Suggestions are made to indicate how experimental facilities (such as cryogenic windtunnels) and computational fluid dynamics might ...

The role of unsteady aerodynamics in aeroacoustics
1st National Fluid Dynamics Conference, 1988The role of acoustics and unsteady aerodynamics research in understanding the fundamental physics of time-dependent fluid phenomena is reviewed. The key issues are illustrated by considering the sound radiation of turbulent jets and the aeroacoustics of rotating bodies such as helicopter rotors. The importance of computational methods as a link between

Control of Unsteady Aerodynamic Forces
1990Abstract : The aerodynamic properties of an airfoil under unsteady conditions are very different from ones in steady conditions because the vortex generated by unsteady separation greatly modifies the loading on the wing. In this study, a fundamental approach was taken to investigate the lift and the velocity field of unsteady airfoils.

Reduced-Order Models for Nonlinear Unsteady Aerodynamics
AIAA Journal, 2000Two reduced-order modeling approaches for the evaluation of nonlinear aerodynamic forces based on CFD computations are presented. These reducedorder models (ROMs) provide a means for rapid calculation of frequency-domain generalized aerodynamic forces, which can be used in traditional flutter analysis scheme, to calculate flutter characteristics about ...
