A study on aerodynamics and mechanisms of elementary morphing models for flapping wing in bat forward flight [PDF]
Applied Mathematics and Mechanics (English Edition), 36(5),
669-680 (2015), 2014 The large active wing deformation is a significant way to generate high aerodynamic forces required in bat flapping flight. Besides the twisting, the elementary morphing models of a bat wing are proposed, such as wing-bending in the spanwise direction, wing-cambering in the chordwise direction, and wing area-changing.
