Noise Reduction of UAV Using Biomimetic Propellers with Varied Morphologies Leading-edge Serration被引量：3
《Journal of Bionic Engineering》2020年第4期767-779,共13页Yuliang Wei Feng Xu Shiyuan Bian Deyi Kong 
the National Natural Science Foundation of China(No.11774355).Special thanks are extended to the Wildlife Park,Hefei,Anhui,China for providing the feathers of owls and hawks.
The Leading-Edge(LE)serrations on owls'wings are known to be responsible for silent flight.However,this design has rarely been applied to reduce the noise of rotational rotor propellers and the morphologies of the exi...
