An Analytic and Experimental Investigation of the Wakes Behind Flapped and Unflapped Wings

Abstract

An analytic and experimental program was undertaken to define the near wake structure behind flapped and unflapped wings. The vortex wake structure is determined, given the wing lift and drag distributions with models developed in the spirit of Betz. A procedure to estimate the turbulent kinetic energy distribution in the vortex is also given, as well as a method to determine discrete vortex positions in the downstream wake.
