The use of computational fluid dynamics to assess the hull resistance of concept autonomous underwater vehicles [PDF]

open access: yes, 2007
Autonomous Underwater Vehicles (AUV’s) provide an important tool for collecting detailed scientific information from the oceans depths. The hull resistance of an AUV is an important factor in determining the powering requirements and range of the vehicle.

Research on Energy Supply System Applied to Autonomous Underwater Observation Vehicles

open access: yesApplied Bionics and Biomechanics, 2022
The discharge characteristics of seawater batteries can be used to prolong the working hours of autonomous underwater observation vehicles. However, the output voltage level of the seawater battery is low, so it cannot directly be used to power supply ...

A theoretical approach to facilitating transition phase motion in a positively buoyant autonomous underwater vehicle [PDF]

open access: yes, 2009
Positively buoyant autonomous underwater vehicles (AUVs) operate at survey speeds with a pitch angle that ismaintained through application of the control surfaces, sufficient to generate hydrodynamic forces to counteract theexcess buoyancy. To facilitate
