Aerodynamic effects of flexibility in flapping wings [PDF]
Journal of The Royal Society Interface, 2009 Recent work on the aerodynamics of flapping flight reveals fundamental differences in the mechanisms of aerodynamic force generation between fixed and flapping wings. When fixed wings translate at high angles of attack, they periodically generate and shed leading and trailing edge vortices as reflected in their fluctuating aerodynamic force traces and ...

Multimodal Locomotion of Soft Robots
Advanced Intelligent Systems, EarlyView.This review comprehensively surveys recent advances in multimodal locomotion within soft robotics. Typical locomotion modes are summarized and categorized. Furthermore, the underlying mechanisms enabling multimodal locomotion are discussed and classified into three primary categories: active control‐based, reconfiguration‐based, and environment ...

Ground Effect on Flapping Wing
Procedia Engineering, 2013 AbstractThe ground effect on flapping wing is investigated numerically based on the immersed boundary-lattice Boltzmann method. A NACA0012 airfoil is considered in this work. The airfoil executes oscillation along vertical direction near ground. The simulations have been carried out for some parameters including the distance between the foil and the ...
