Biophysical Principles of High-Speed Avian Wing Architecture

A peregrine falcon can fly at a higher speed when loaded with a given payload compared to aircrafts of equivalent configurations. At the same time, they cannot utilize composite materials such as carbon fibers. What gave them this capability?

In this research, the effect of geometric layout on aeroelasticity is explored, showing that the M-shaped geometry of the falcon's wings, biologically known as the high-speed wing configuration, can improve aeroelasticity responses without changes in material and structures. It is applicable to small drones so that they can fly faster without significant additional costs.

Given the faster speeds and undiminished aerodynamic efficiency, adopting this design is useful in surveys needing large coverage within agriculture, environment, and other industries.
