Multibody Modelling of High-Lift Mechanisms of Modern Transport Aircraft
2013
High-lift devices of transport aircraft reshape the wing in order to increase the lift during certain portions of flight. They are moved by complex mechanisms. To simulate the behaviour of high-lift devices under aerodynamic loads an elastic multibody model is developed that comprises the flap and slat mechanisms and an elastic wing structure. Elastic bodies are described by finite element models that are integrated into the multibody formulation by modal approaches. Simulation examples show applications of the model for the analysis of critical load cases.
