On the Influence of Time-Varying Flow Velocity on Unsteady Aerodynamics

van der Wall, Berend G. and Leishman, Gordon (1994) On the Influence of Time-Varying Flow Velocity on Unsteady Aerodynamics. Journal of the American Helicopter Society, 39 (4), pp. 25-36. ISSN 0002-8711

Abstract

The effects of a periodic free-stream velocity on the unsteady aerodynamics of an airfoil in incompressible flow are examined. Existing theories are reviewed, and their simplifications and limitations are properly identified. A new general aerodynamic theory for an airfoil undergoing a combination of harmonic pitching, plunging and fore-aft motion is presented. An extension to arbitrary free-stream velocity variations and arbitrary airfoil motion is also given. The theoretical results are validated against numerical predictions made by a modern Euler code.
