Abstract
A contribution for the assessment of the static and dynamic aerodynamic behavior of a
generic UCAV configuration with control devices using CFD methods is given. For the CFD
simulations the unstructured grid based DLR TAU-Code and the structured grid based
NLR solver ENSOLV are used. The numerical methods are verified by experimental wind
tunnel data. The current investigations should provide a contribution to assess the prediction
capability of control device effectiveness using CFD methods. The presented computational
results for the assessment will be validated by dedicated experimental data. Furthermore, it
should support the understanding of the flow physics around the trailing edge control
devices of highly swept configurations with a vortex dominated flow field. Design
requirements should be able draw by analyzing the interaction between the vortical flow and
the control devices. The present work is part of the NATO STO/AVT Task Group AVT-201
