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 Mean Power of Forces and Moments in Unsteady Aerodynamics
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1992AbstractThe balance of mechanical energy serves as the starting point for a unified and consistent approach to the two basic and inherent mechanisms in unsteady aerodynamics, propulsion and flutter. Both phenomena are mutually dependent and interchangeable with each other by a mere variation of the reduced frequency as the governing magnitude with ...

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.
