The current investigations look at the vortical flow physics and aerodynamic performance of a generic sharp leading-edge multi-delta-wing configuration. This work is part of the DLR project Diabolo looking at technologies and design requirements for next-generation fighter aircraft. The core of the investigation is a common planform geometry to demonstrate the design capability needed. Based on the initial planform, several design tasks in different domains have to be conducted. The present paper is dealing with the aerodynamic task to evaluate the effect of vortex interaction over the configuration progressing from the forebody, strakes, and main wing at asymmetric on flow conditions. The focus is on the roll stability at medium to high angle of attack. The aim is to find a planform and control surface setup which effects the vortex interaction on the main wing in a way to provide a stable aerodynamic roll without taking vertical and horizontal tail planes into consideration at this stage.
