Feasibility Study on Unmanned Aerial Vehicle-Based Undersea Acoustic Sensing [PDF]

Journal of Oceanography and Marine Research, 2019
An unmanned aerial vehicle (UAV) system with hybrid air-water quadcopter platform, named AquaQuad, was developed in the Department of Mechanical and Aerospace Engineering, Naval Postgraduate School. It can land on ocean surface with different sea-states for communication and provide undersea passive acoustic sensing.

Fuzzy logic for depth control of Unmanned Undersea Vehicles

IEEE Journal of Oceanic Engineering, 1995
Fuzzy logic is a viable control strategy for depth control of undersea vehicles. It has been applied to the low speed ballast control problem for ARPA's unmanned undersea vehicle (UUV), designed and built by Draper. A fuzzy logic controller has been designed and tested in simulation that issues pump commands to effect changes in the UUV depth, while ...

Bio-inspired unmanned undersea vehicle

SPIE Proceedings, 2010
Biological systems in ocean environment provide all the desired features required for design of unmanned undersea vehicles. We noticed the uniqueness and simplicity in the design of rowing medusa and have successfully demonstrated working prototypes of Aurelia Aurita. In this study, we demonstrate the effect of bell joints in reducing the contraction

Recovering unmanned undersea vehicles with a homing and docking sonar

Proceedings of OCEANS 2005 MTS/IEEE, 2005
There is a great deal of interest in deploying and recovering an unmanned undersea vehicle (UUV) with a submarine or a surface ship. This paper describes a homing and docking sonar (HDS) that was developed for a 21-inch diameter UUV and host platform.
