The hydrodynamics and mechanics team have several tasks that aims to facilitate algorithms,to guarantee safety of electronic components and to idealize and fabricate our AUV structure.

Tasks such as modelling the external and internal CAD structure of the AUV ,guaranteeing its tightness,analysing the material response when mechanically requested and its behavior when in underwater movement and last but not least manufacturing extra projects (torpedoes , marker drop and mechanical arm).

At the moment we are divided as :

1) Structure : In charge of modelling the 3D CAD of the AUV external parts (by making use of SolidWorks) and manufacturing the external parts like the principal hull, frame and any necessary attachment (such as the battery attachment). Besides that they are responsible for choosing the fastening elements.

2) Internal part : Also in charge of modelling the 3D CAD of the AUV internal parts (also by making use of SolidWorks) and manufacturing the internal parts making sure that the projects are always well integrated with the electronics team.

3) Tightness : This sub area has one of the most important tasks in the making of the AUV.The task of guaranteeing the safety of the electronic components by making use of the sealing elements like O’rings that are calculated by taking into consideration different aspects of the part to be sealed.

4) Simulation : They are responsible for the CFD (Computational Fluid Dynamics) and FEA (Finite element method) simulations of different parts of the AUV.
