描述It has been recognized by the European Union (EU) that the survival of the Aeronautical Industries of Europe in the highly competitive World Aviation Market is strongly dependent on such factors as time-to-market of a new or derivative aircraft and on its manufacturing costs but also on the achievement of a competitive technological advantage by which an increased market share can be gained. Cooperative research is therefore continuously encouraged and co-financed by the European Union in order to strengthen the scientific and technological base of the Aeronautical Industries thus facilitating the future design and manufacture of civil air­ craft products and providing the technological edge needed for survival. Targets of research within Area 3, Aeronautics, of the Industrial and Materials Technology Programme (1991 - 1993) have been identified to be aircraft efficiency, cost effectiveness and environmental im­ pact. Concerning aircraft efficiency - relevant to the present research - a reduction in aircraft drag of 10010, a reduction in aircraft fuel consumption of 30010 and a reduction in airframe, en­ gine and system weight of 20% are envisaged. Meeting these objectives has, of

Basic Study of Passive Control Applied to a Two-dimensional Transonic Interactionly outbalances the gain in wave drag. Also, the rugosity of the holes is an important source of drag (excrescence drag) which contributes to compromise the potential benefit of the passive control technique. The most commonly used turbulence models give poor results, even in the solid wall reference

Numerical Investigation of the Passive Shock Control on Transonic Airfoils through an Euler/Boundaryn the aerodynamic characteristics of airfoils is concerned, the numerical investigation performed with the present method on the airfoils considered in the project has confirmed the main results of the experiments and of other numerical analyses.

Transonic Airfoil Flow Prediction with Shock Boundary Layer Interaction Control (SBLIC) by a Time-AcSHOCK..In the unsteady cases a surprisingly good correspondence between calculation and experiment was found with respect to the buffet frequency. However, the start of shock oscillations was predicted at slightly higher Mach numbers / incidences compared to the experiment. In general the 2D Navier-
