Lift observation conveys object weight distribution but partly enhances predictive lift planning [PDF]
Journal of Neurophysiology, 2020 AbstractObservation of object lifting allows updating of internal object representations for object weight, in turn enabling accurate scaling of fingertip forces when lifting the same object. Here, we investigated whether lift observation also enables updating of internal representations for an object’s weight distribution.

Evolution of the leading-edge vortex over a flapping wing mechanism
Journal of Mechanical Engineering and Sciences, 2020 Leading-edge vortex governs the aerodynamic force production of flapping wing flyers. The primary factor for lift enhancement is the leading-edge vortex (LEV) that allows for stall delay that is associated with unsteady fluid flow and thus generating ...

Coriolis effects enhance lift on revolving wings [PDF]
Physical Review E, 2015 At high angles of attack, an aircraft wing stalls. This dreaded event is characterized by the development of a leading edge vortex on the upper surface of the wing, followed by its shedding which causes a drastic drop in the aerodynamic lift. At similar angles of attack, the leading edge vortex on an insect wing or an autorotating seed membrane remains

Application Research of Flow Control Using Co-flow Jet on a Vertical Tail
Hangkong gongcheng jinzhan, 2022 The aerodynamic characteristics of the vertical tail of an aircraft are directly related to the size and weight of the vertical tail. Increasing the lift force of the vertical tail using flow control can further reduce the size of the vertical tail,which
