Mesh morphing of an airfoil with foldable Krueger flap

Krueger flap is a famous kind of lifting enhancement device fitted onto the leading edge of the wings. The flap remains retracted during the cruise and is hidden inside the main wing. During take-off and landing, it will be deployed by rotating around a hinge at the leading edge of the main wing to increase the wing camber and get a higher maximum lift coefficient. In this case study, as part of the UHURA H2020 project (CORDIS)¬†coordinated by DLR, the simulation of the deployment process of a foldable Krueger flap is presented. The process of the deployment of the flap…
