Aircraft Loads - A Wide Range of Disciplinary and Process-Related Issues in Simulation and Experiment (original) (raw)

The estimation of the loads is a key aspect of the extensive aircraft design process and also an important task during the life-time of an aircraft. DLRs joint efforts regarding the loads estimation and application, the latter also in view of structural aspects, both simulation based and experimentally were part of the DLR project KonTeKst (2016-2019). The loads activities cover the loads process, with one focus on the component loads process. Therein, the various possibilities to introduce loads to the structure were investigated as well as the consideration of flight control methods. On the structural side experiments were executed to estimate damage tolerance parameters for composite structures. Furthermore, fatigue and damage tolerance properties of metallic fuselage structures were estimated. Therefore, a novel AlCuLi sheet material was investigated regarding anisotropic fatigue crack growth. Finally, the consideration of aerodynamic loads for high lift configurations was inves...
