摘要：
In this paper, a theoretical study is conducted to investigate the propulsive performance of two flapping foils with the inline arrangement. At first, we consider the propulsive performance of two flapping foils when they are relative static to each other, that is, the horizontal gap between the foils is fixed. Then, we provide a model to consider the dynamic stability of the two-foil system when the relative movement between them has occurred, that is, the horizontal gap between the two foils can be changed depending on the propulsive force acting on the foil. This work provides helpful suggestions for managing the trajectories and energy cost of multiple bio-inspired robotics.
