A New Approach to Underwater Gliders Modelling

The article describes the importance of underwater gliders. Although the underwater gliders (UGs) are autonomous underwater vehicles (AUVs), they still have a different propulsion system. That is, these underwater gliders use propulsion with variable buoyancy compared to propellers or thrusters. The presented model consists of body, wings, rudder, antenna, stern and nose. Moreover, this model is made of aluminum alloy 6061. With the help of the finite element method (FEM), the shear and octahedral stresses of an underwater glider are determined. In addition, with the help of the computational fluid dynamics (CFD), the velocity is determined. Launching and retrieving such an underwater glider from the sea is easy under normal temperature conditions. The underwater glider (UG) can also move slowly (ex. 0.21 m/s) only up and down through the sea.
