... , the quasi-steady wing force. Following the same procedure, the force on the flat wing was calculated, denoted by F fluid,wing,flat,QS . The lift and drag coefficients of a flapping wing were estimated using the cross-flow vortex model ( Bandyopadhyay et al., 2008 ), where pre-stall steady wing...

...Yuan Lu; Gong Xin Shen SUMMARY Following the identification and confirmation of the substructures of the leading-edge vortex (LEV) system on flapping wings, it is apparent that the actual LEV structures could be more complex than had been estimated in previous investigations. In this experimental...

...Z. Jane Wang SUMMARY To seek the simplest efficient flapping wing motions and understand their relation to steady flight, a two-stroke model in the quasi-steady limit was analyzed. It was found that a family of two-stroke flapping motions have aerodynamic efficiency close to, but slightly lower...
