More than 1,000 species of bats have hand membrane wings, meaning that their fingers are essentially “webbed” and connected by a flexible membrane. But understanding how bats use their wings to manipulate the air around them is extremely challenging—primarily because both experimental measurements on live creatures and the related computer analysis are quite complex.
In Virginia Tech’s study of fruit bat wings, the researchers used experimental measurements of the movements of the bats’ wings in real flight, and then used analysis software to see the direct relationship between wing motion and airflow around the bat wing. They report their findings in the journal Physics of Fluids.
“Bats have different wing shapes and sizes, depending on their evolutionary function.
