This work deals with the investigation of continuously deflectable high-lift devices. The aim of this work is to derive optimal high-lift settings for off-design conditions and to evaluate the benefits of this technology. Off-design is related in this context to airport, aircraft and atmospheric specific conditions. Within the work a fully automatized process chain (high-fidelity methods are used) is implemented to generate an aerodynamic database for various high-lift settings. This data base is used by a preliminary design tool to simulate the overall aircraft for take-off, approach and landing at off-design. The resulting data are fed in a response surface model (RSM) to obtain the overall behavior for the slat/flap deflection angle domain. The interpolated values are used to derive optimal high-lift settings. The results show consistent behavior. It is found that for take-off valuable benefits can be achieved. For landing the results indicate that a further flap deflection than the standard landing setting is beneficial.
