Design optimization and combined numerical-experimental investigation of the hydrodynamic performance of underwater disc-shaped gliders

AIP Advances
The disk-shaped underwater glider is widely used in marine environmental monitoring due to its excellent underwater gliding capability. Gliders can be equipped with various sensors such as hydrophones and other acoustic acquisition devices.

A Study of the Three-Dimensional Localization of an Underwater Glider Hull Using a Hierarchical Convolutional Neural Network Vision Encoder and a Variable Mixture-of-Experts Transformer

Remote Sensing
Although underwater gliders are highly energy-efficient platforms capable of long-duration and large-scale ocean observation, their lack of self-propulsion requires external assistance for recovery upon mission completion.

Acoustic tag tracking: first experiments [PDF]

, 2018
Nowadays, the use of autonomous vehicles for ocean research has increased, since these vehicles have a better cost/performance ratio than crewed vessels or oceanographic ships.

Simulation of an underwater glider

, 2007
Underwater gliders are being proposed as an alternative to the resource intensive and costly shipboard methods of oceanographic data collection. One such underwater vehicle currently in operation is the SLOCUM Glider. The purpose of the present work is to devise a dynamic simulation for the SLOCUM Glider that allows the vehicle's motion to be predicted

Wing shape optimization for an air-launched underwater glider considering impact loads and gliding performance

International Journal of Naval Architecture and Ocean Engineering
The air-launched underwater glider has two typical scenarios that need to be specially considered in its design: the water impact stage after air-launched deployment and the gliding stage of the glider in the water.
