Abstract

In this study the aerodynamics of wings using an active high-lift system are investigated. The target is the flight mechanical description of the spanwise forces and resulting moments and the influence of the active high-lift system to their distribution. The high-lift system is a blown flap system divided into six segments per wing. Each segment is assumed to be individually controlled, so the system shall be used for aircraft control and system failure management. This work presents a flight mechanical model for fast-time simulation of flight dynamics, which has been derived from high-fidelity CFD results. An assessment of single segment system failures will be presented including recommendations for compensation of either lift or rolling moment loss. For this investigation, the compensation is required to act at the same wing on which the failure appears. Thus, the potential for an increase of system reliability shall be proven. The results show that less performance investment is necessary to compensate the rolling moment of a failing segment instead of its lift. However, large performance increases for the remaining wing segments occur for some of the failure cases.
