Abstract

Artificial wings composed of rigid and flexible materials enable flapping flight accompanied by sound. Understanding the acoustics of natural insect wings allowed explaining basic mechanisms of sound generation by artificial wings. This work proposes to use metamaterial surface patterns for controlling the acoustic and aerodynamic characteristics of a wing. For this, we developed multi-parameter and machine-learning optimization procedures aimed at increasing the lift and manipulating the produced sound by tuning the pattern design.
