Fin-based propulsion systems of fishes perform well for both high-speed cruising and high maneuverability, which inspires different fin propulsors for autonomous underwater vehicles. Here, we present a novel fish-fin actuator composed of a series of shape memory alloy (SMA) plate couple. Both SMA plates, whose microstructure is either martensite or austenite, are individually arranged in parallel...
Many fishes use undulatory fin to propel themselves through the underwater environment. These locomotor mechanisms have a popular interest to many researchers. In the present study, we perform a three-dimensional unsteady computation of an undulatory mechanical fin that is driven by shape memory alloy (SMA). The objective of the computation is to investigate the fluid dynamics of force production...
Crucians propel themselves through the water primarily either with their body and tail (axial-based locomotion) at high swimming speed or with their greatly expanded pectoral fins (pectoral-fin-based locomotion) at low swimming speed. They also use their pectoral fins to adjust stability in still motion. In this paper, we present recent experimental research on pectoral fin structure, fin locomotion,...
