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 ...

BUFFALO, N.Y. -- The secret to the flight of the hummingbird and other tiny birds and insects lies in the looping, swirling flow of air, called a vortex, that their flapping wings create. These ...

In this historic 1946 photo from the U.S. space agency, a semispan airplane model and flow-direction vane mounted on wing of P-51D airplane for transonic tests by wing-flow method. The National ...

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

The lectures attempt to provide an overview of image-based aerodynamics measurement techniques and their applications for students and researchers. The presented materials include the research results ...
