“…However, low speed is an inherent characteristic of UGs. Although some research institutions have adopted hybrid driven [50,51], vector propulsion [52], and other methods to improve the maneuverability of UGs, it has also brought the disadvantages of high energy consumption and complex structure. Thus, how to improve the maneuverability and application area of the UG while maintaining a low speed is of great research value.…”

A disc-type underwater glider (DTUG) has a highly symmetrical shape and is characterized by omnidirectional characteristics and high maneuverability in small bodies of water. To further explore the disc shape’s advantages and characteristics in steering motion, DTUG motion was simulated by Matlab/Simulink. Based on the structural characteristics of DTUG, the motion control equations were established. The simulation of DTUG’s steering motion is carried out and compared with a previous DTUG (LUNA). The sensitivity analysis and Lyapunov stability analysis were also conducted. The results showed that the in situ steering motion can be realized by controlling the position of the center of gravity (CG) of DTUG without moving vertically, which facilitates rapid adjustment of the yaw angle and flexible movement in small bodies of water. The in situ steering motion was significantly affected by the control parameters. The parameter that had the greatest effect on it can be obtained through sensitivity analysis, which can guide DTUG to better adjust the yaw angle under different conditions. The stability analysis showed that the DTUG can remain stable within the range of the control parameter.

“…1. This blade profile is widely used on marine propellers due to its favourable cavitation avoidance and structural characteristics (Carlton, 2012). While the former is not of concern here due to the vehicle typically operating at high static pressures, the relatively thick trailing edge and large cross-sectional area of the foil were deemed favourable due to the intention to manufacture the propeller blades using 3D printing.…”

“…For this reason, several vehicles in use today employ small thruster units intended to provide an additional means of propulsion. However, they are used mostly for overcoming currents and maintaining steady rates of ascent or descent rather than to provide the ability to operate the vehicle as a conventional AUV (Claus et al, 2010;Chen et al, 2016;Isa et al, 2014). Thrusters used on ROVs or conventional AUVs typically need to be operated over a wide range * Corresponding author at: Maritime Research Institute Netherlands (MARIN), 2 Haagsteeg, 6708 PM, Wageningen, The Netherlands.…”

Autonomous underwater vehicles play an essential role in geophysical data collection, deep water mining, seafloor mapping, ocean exploration, and in many other related activities starting from military to scientific applications. A detailed understanding of hydrodynamic characteristics will lead to better design, better control, and optimal path planning of autonomous underwater vehicles in the deepest corner of oceans. This article will provide a detailed review of the hydrodynamic characteristics of autonomous underwater vehicles, starting from different experimental techniques used in the analysis of hydrodynamic parameters, methods used for fixing the autonomous underwater vehicles in towing tank, instruments used for measurement of the hydrodynamic parameters. Furthermore, numerical methods employed in performing computational analysis, hydrodynamics-based shape optimization, studies on drag reduction, and finally a detailed list of turbulence models used in the computational fluid dynamics–related numerical simulations. The hydrodynamics-based optimal shape of the autonomous underwater vehicles, the best technique to predict the hydrodynamic parameters, and the best turbulence model for the computational fluid dynamics–based prediction of hydrodynamic parameters will be recommended. At last, the hydrodynamic characteristics of different bio-inspired autonomous underwater vehicles are discussed.
