The Role of Vanes in the Damping of Bird Feathers
《Journal of Bionic Engineering》2023年第4期1646-1655,共10页Kai Deng Hamed Rajabi Alexander Kovalev Clemens F.Schaber Zhendong Dai Stanislav N.Gorb 
financially supported by Sino-German Center for Research Promotion (Grant no.GZ1154).
Bird feathers sustain bending and vibrations during flight.Such unwanted vibrations could potentially cause noise and flight instabilities.Damping could alter the system response,resulting in improving quiet flight,st...

Effects of Morphological Integrity of Secondary Feather on Their Drag Reduction in Pigeons
《Journal of Bionic Engineering》2022年第5期1422-1438,共17页Qian Li Huan Shen Qingfei Han Aihong Ji Zhendong Dai Stanislav N.Gorb 
This work was supported by the Chinesisch-Deutsches Zentrumfur Wissenschaftsforderung to SNG and ZDD(Grant No.GZl154);the National Natural Science Foundation of China(Grant Nos.51875281,51861135306)。
Flight feathers of birds interact with the air flow during flight.How the observed low drag and high lift values at wind speeds from 9.0 to 19.8 m/s can be achieved due to the feather aerodynamics remains unknown.In t...
