Design Work for the A3XX High-Lift-Wing

The A3XX configuration being dimensioned larger than any flying aircraft must be operated in the given airport infrastructure. The high-lift system has to provide this ability while being designed to minimum complexity and weight. The aerodynamic design work conducted by EADS Airbus Germany for the design of the A3XX high-lift wing is carried out based on CFD and windtunnel experiments as major tools for configuration development. The available and developed CFD-design environment and the windtunnel infrastructure led to a configuration providing an aerodynamic performance fulfilling these challenging requirements. In parallel least system complexity of the leading edge and trailing edge system was maintained finally leading to a high-lift system which represents an optimised solution under multidisciplinary constraints.
