We have found that low levels of helium injection near the leading edge stabilizes the turbulent boundary layer, apparently causing a reverse transition to laminar flow to take place. These results ...

The boundary layer, a tiny layer on the surface of a body in a flowing fluid, such as an airplane wing in the air, is of paramount importance for the future of flight. Just over 100 years ago, Ludwig ...

The aim is to make aviation in Europe climate-neutral by 2050. An important part of this is reducing the drag of future aircraft, with the wings playing a major role. The wings not only generate the ...

A body moving through a fluid experiences a drag force, which is usually divided into two components: frictional drag, and pressure drag. Frictional drag comes from friction between the fluid and the ...

In the quest for greater efficiency of large transport aircraft, efforts to reduce wing drag through conventional aerodynamic tweaks have largely been exhausted, in the view of Airbus senior ...
