Leakage of an eagle flight feather and its influence on the aerodynamics
《Chinese Physics B》2021年第3期335-345,共11页Di Tang Dawei Liu Yin Yang Yang Li Xipeng Huang Kai Liu 
Project supported by the National Natural Science Foundation of China(Grant No.51705459);the Natural Science Foundation of Zhejiang Province,China(Grant No.LY20E050022).
We investigate how the barb of bird feathers is changed along both the rachis and barb.To investigate the microstructures and the mechanical behaviors of barbs,a series of barbs are manually cut from an eagle’s prima...

Measuring the flexibility matrix of an eagle’s flight feather and a method to estimate the stiffness distribution
《Chinese Physics B》2019年第7期305-311,共7页Di Tang Hai Zhu Wei Yuan Zhongyong Fan Mingxia Lei 
Project supported by the National Natural Science Foundation of China(Grant No.51705459);the China Postdoctoral Science Foundation
Flight feathers stand out with extraordinary mechanical properties for flight because they are lightweight but stiff enough.Their elasticity has great effects on the aerodynamics, resulting in aeroelasticity.Our prima...
