Numerical Simulation Of Maneuvering Combat Aircraft

An overview about recent results of the DLR-Project SikMa-"Simulation of Complex Maneuvers" is presented. The objective of the SikMa-Project is to develop a numerical toot to simulate the unsteady aerodynamics of a free flying aeroelastic combat aircraft; by rise of coupled aerodynamic, flight-mechanic and aeroelastic computations. To achieve this objective, the unstructured, time accurate flow-solver TAU is coupled with a computational module, solving the flight-mechanic equations of motion and a structural mechanics code determining the structural deformations. By use of an overlapping grid technique (chimera), simulations of a complex configuration with movable control-surfaces is possible.
