New designs of flying robots are inspired by the Fruit bats. Researchers have studied the way these bats flap their wings rapidly in flight. They have also studied how these bats use their wings in manipulating the air around them.
Scientists said understanding the processes of the wings of Fruit bats could help the engineers in designing tiny flying robots.
Professor Danesh Tafti said the wings of these Fruit bats have different shapes and sizes based on the evolutionary function. He added further that bats are very agile and have the capability of changing their flight path very quickly. It is study of interest to understand how the bats do this.
Tafti is professor in the department of mechanical engineering and also director of the High Performance Computational Fluid Thermal Science and Engineering Lab at the Virginia Tech.
Researchers said the Fruit bats along with more than 1,000 other species of it have such wings that are made of flexible and webbed membranes and these are connected to their fingers. The weight of Fruit bats are just one ounce and their each wings measures around 6.7 inches.
Scientists collected measurements of live flying bats to understand how they flap their wings. They used specially made software to learn the relationship between its movements and the airflow motion around the wings.
The researchers found the bats could change movement of the wings to maximize the forces that is generated by their flapping process. This mean they can maximize the wing to about 30 percent to enhance the favorable forces as it pushes downward.
