The transition of airflow from laminar to turbulent state is a major contributor to aerodynamic drag and consequently aircraft emissions. Often, unavoidable modifications of the wing surface, such as panel joints or skin deformations decrease the extent of laminar airflow by promoting transition. However, through our research, we showed that this is not always the case. In a recent breakthrough, our team discovered the “Delft Laminar Hump”, a passive smooth surface modification.
