Abstract

Abstract. This paper presents results of the numerical part of the DLR-ONERA project WIONA (Wing with Oscillating Nacelle). Unsteady aerodynamics of a generic wingpylon- nacelle configuration is investigated and CFD simulation tools are validated with test results and against one another. The results show that for the present configuration unsteady aerodynamics for different forced oscillations, of the whole model as well as of pylon and nacelle alone, can be precisely predicted in transonic flow including shock induced separation.
