Autonomous underwater vehicles (AUVs) are transforming the way we explore the ocean, allowing longer explorations in a variety of ocean conditions. Biological-based designs could enhance the mobility and efficiency of future AUV's. In particular, flexible ribbon-fin propulsion represents an ideal propulsion mechanism for highly maneuverable vehicles. However, the hydrodynamics, fluid-fin interaction and maneuvers using elongated fin propulsion are still poorly understood. The outcome of this research will provide insights into the hydrodynamics of flexible ribbon fin-base propulsion during different maneuvers. Two students, one graduate student and one undergraduate, will be supported by this award to research possible ribbon-fin propulsion designs. The principal investigator will also present the research to a group of K-12 students participating in a local ocean science camp program and develop a new graduate and undergraduate course that will focus on the hydrodynamics of animal locomotion in the broad context of ocean exploration, biology, underwater vehicle design and fluid mechanics.This work will study the hydrodynamics of a flexible undulating ribbon fin using a robotic fin as a model. In particular, the objectives are: 1) examine the effect of flexibility and morphology in the hydrodynamics performance, 2) investigate the interconnection of flow structure, propulsion efficiency and actuation control, and 3) study maneuvers and flow control. The series of experiments will include measurement of fin kinematics, propulsive forces, and flow measurements using particle image velocimetry (PIV). The experiments will be performed at the Hydrodynamics Laboratory at Florida Atlantic University.

自动的水下车辆（AUV）正在改变我们探索海洋的方式，从而在各种海洋条件下进行更长的探索。基于生物的设计可以提高未来AUV的流动性和效率。尤其是，柔性丝网推进代表了高度可操纵车辆的理想推进机制。然而，使用细长的鳍动力的流体动力学，流体 - 鳍相互作用和操纵仍然知之甚少。这项研究的结果将提供对不同动作过程中柔性色带推进的流体动力学的见解。该奖项将支持两名学生，一名研究生和一名本科生，以研究可能的缎带推进设计。主要研究人员还将向参加当地海洋科学训练营计划的一组K-12学生展示这项研究，并开发新的毕业生和本科课程，该课程将重点放在海洋探索，生物学，水下车辆设计和流体机制的广泛背景下的动物运动的流体动力学上。这些工作将研究使用固定型填充的动物限制动物限制的动力学，并将其用于机器人限制的模型。特别是目标是：1）检查灵活性和形态在流体动力性能中的影响，2）研究流动结构，推进效率和驱动控制的互连，以及3）研究动作和流动控制。一系列实验将包括使用粒子图像速度法（PIV）测量FIN运动学，推进力和流量测量。实验将在佛罗里达大西洋大学的流体力学实验室进行。
