An experimental investigation on the acoustic performance of a flapping wing Micro-Air-Vehicle

摘要

An experimental study was conducted to assess the acoustic performance of a two-winged Flapping-Wing Micro-Air-Vehicle (FW-MAV) with various wing materials and wing structure configurations for flapping flight applications. It was concluded that highly elastic materials could significantly reduce the flapping wing noise in a wide spectrum of audible frequencies. Furthermore, a dielectric elastomer (DE) which is a lightweight and highly elastic smart material has been preliminarily investigated for its potential applications in the quiet FW-MAV under the passive control scheme.
