"Results of the ASAM research project regarding the design of composite flaps for high lift and LC&A devices"

In the frame of the EU 7th Framework Technology Initiative Green Regional Aircraft project, Novotech Advanced Aerospace Technology and SIEMENS LMS (Belgium) have carried out an investigation on advanced design and simulation methods for load control and alleviation devices and high lift devices. The research focused on novel methods for modelling of aerodynamic loads on flexible bodies, modelling of actuators and methods for concept configuration. Also a method for sizing of composite structures has been established. Therefore multi-body simulation tools have been extended and a composite structural sizing method has been developed. The novel methods have been evaluated by preliminary and detailed conceptual design studies of 3 mechanisms, Krueger Flap, Single Slotted flap and load control and alleviation devices, for a Geared Turbo Fan regional A/C. Overall behavior of integrated systems using a co-simulation approach as driving in the design, in particular the integration of the most suitable simulation tools in the different phases of the project, will be presented.
