To better understand the aerodynamic mechanisms of the wings during 3 different stages, authors used CFD methods to analyze the aerodynamic characteristics of the coupled movements of the 5 kinematic ...

In order to enhance aircraft efficiency designers are increasingly utilizing lightweight, high aspect ratio wing designs. This is because lower weight means less energy is required to keep the ...

Abstract: Wings experiencing large flow disturbances often experience massive flow separation resulting in shear layers and the formation of strong vortices. These vortices typically lead to large ...

Researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), in collaboration with Airbus, have completed a successful world première – for the first time, they have ...

Researchers once wanted to build aircraft wings based on compliant systems, which would continually change shape in response to the air flow resistance, obviating the need for rigid flap and rudder ...

The objective of the European Cleansky project is to develop new technologies for future aircraft enabling a 20- 30% fuel burn reduction and related CO2 emissions and a similar reduction in noise ...

Larger and more powerful engines are making flying more efficient. These gigantic main engines take up more space on the wings of modern passenger aircraft. However, they influence the flow over the ...

Grasshopper’s gangly, awkward flight could solve the biggest power problems in robotics. Standard micro-bots are modeled ...
