Unsteady transonic wing nacelle interference for different oscillatory modes
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
