Active Flow Control Activities at Onera

Abstract : In 1997 O.N.E.R.A (French National Aerospace Research Establishment) created a multidisciplinary project on the subject of active flow control. Experimental work computational fluid dynamic studies modelling and synthesis of control laws constitute the main activities of this project. The investigations include laminarity control buffet control in transonic conditions and control of separated flows and vortices. This document presents the results obtained during some of these activities.
