Within a narrow band of flight conditions in the transonic regime, interactions between shock-
waves and intermittently separated shear layers result in large amplitude, self-sustained …

The control of the transonic buffet phenomenon over a half-model with a swept wing has
been investigated in the S3Ch wind tunnel of the ONERA Meudon center in the framework of …

The objective of this paper is to present an overview of the work performed at Onera over the
last decade on the characterization and control of the buffet phenomenon. This aerodynamic …

The purpose of this paper is to present an overview of existing actuators at Onera for active
flow control. These actuators are used for various applications in wind tunnel tests, from 2D …

I. Introduction n transonic flow conditions, the shock wave/boundary layer interaction
induces a flow separation on the suction side of the wing which depending on the aircraft's …

The shock-wave/boundary layer interaction on the upper side of a wing at high Mach
number and/or high angle of attack induces a massive flow separation, which can lead to …

The transonic buffet over large aircraft wings seriously affects flight safety and ride quality,
thus it has been a focus issue for researchers to control transonic buffet through active or …

The presented paper gives an overview of several projects addressing the experimental
characterization and control of the buffet phenomenon on 3D turbulent wings in transonic …

In aerodynamics fluidic actuators are used to modify the main flow around vehicles by
injecting a secondary flow on its surface through slots or holes. The interaction of this …

This paper has the objective to present an overview of recent experimental studies
conducted in the S3Ch transonic wind tunnel of the ONERA Meudon centre. Experimental …
