The aerodynamics of flying snake airfoils in tandem configuration [PDF]
Journal of Experimental Biology, 2021 ABSTRACT Flying snakes flatten their body to form a roughly triangular cross-sectional shape, enabling lift production and horizontal acceleration. While gliding, they also assume an S-shaped posture, which could promote aerodynamic interactions between the fore and the aft body.
