Influence of Vertical Stabilizer on the Aerodynamic Stability of a Generic Multi Delta Wing Aircraft Configuration

The current numerical investigations analyze the influence of the vertical stabilizer on the aerodynamics and aerodynamic stability, especially roll stability, of a multi delta wing configuration. Planform studies established to enhance the rolling moment behavior by means of strakes and wing leading edge slats are taken as a reference for the current vertical tail plane studies. The aim is to identify the differences between the configuration with and without vertical tails. In particular the influence of the vortical flow topology and interaction with the vertical tail planes on the aerodynamic behavior should be identified. This should lead to design recommendations for the current fighter design approaches within the DLR project Diabolo.
