Topic : Design and Implementation of Underwater Autonomous Vehicle (Uav- Varauna)

Authors:C. Sivaprakash || Kusuma.P, Jeevan.N.R, Kishore Kumar.S, Dr. Pauline. A

Abstract:VARUNA is the first autonomous underwater vehicle (AUV) design and builds by our team. Complete the AUV in a sixmonth design cycle, the vehicle is fully modeled using Solid works software and extensively we will simulate the structural and flow analysis with ANSYS, STARCCM+ software ’s and going to manufacture almost entirely in our campus. Grid Independent studies will be carried out for the structural and flow analysis. Various Turbulence models will be select based on the literature survey for the flow analysis. Based on the Grid independent studies simulation is carried out for various speeds for 0.1-0.5 m/sec then only we can neglect the lift forces based on the wet test. During generation of the meshes, attention will be given for refining the meshes near the AUV so that the boundary layer can be resolved properly. Varuna presents a cheaper, stronger, lighter in weight of 27 kg and compact size of 0.8m*0.6m*0.6mas length, width and height of the vehicle and capable of working under 25 m depth. New advancements include full vehicle control of six degrees of freedom, a dual-hull cantilevered electronics rack and hulls, overhauled wire routing for electrical systems, and significant software for mission reliability and robustness. Varuna sensor suite comprises of inertial measurement units (IMUs), two vision cameras, and humidity sensors, water sensors for kill switches, a depth sensor and an internal pressure sensor. Returning features include a vacuum-assisted sealing system; hot-swappable battery pods, unified serial communications, and flexible mission software architecture will be install..
