The paper reports on meshing strategies for modeling of movable control surfaces. In the course of the project ComFliTe, different meshing strategies habe been investigated. As central test cases a generic wing-aileron configuration based on the LANN wing (1) was studied. Approaches based on mesh deformation, the Chimera technique and a combination of Chimera technique and mesh deformation were considered. As second test case a generic wing-spoiler configuration was studied. The challenging thing about the latter test case was that the simulation was supposed to start when the spoiler is still fully recessed in the contour of the wing. The pros and cons of the different modeling approaches applied to the aileron and the spoiler test case are discussed and recommendations for modeling of particularly moving control surfaces are given. In addition, the so-called disturbance velocity approach is presented in the second part of this paper as a very efficient technique for the modeling of atmospheric effects striking an aircraft; e.g. gusts.
