Conceptual Design and Hydrodynamic Research on Unmanned Aquatic Vehicle

Abstract

Autonomous Underwater Vehicles (AUVs) are one of the significant types of aircraft, which are traveled in submarine by the pre-programmed control process. At the present time AUV is being projected for many serious applications together with fault exposure on the dam, tragedy monitoring, naval supervision, and fisheries safety. Interest in AUVs for ocean investigation and mapping, inspection, and forecasting have emerged progressively, in which the AUVs design methods are implemented in submarine are regularly multi-rotor arrangement AUVs. In submerged applications, multi-rotor based AUVs are low proficient in terms maneuvering practicability, existence, as a result, the designer must make available an AUV, which has the high lifetime, high efficient in devise, more secure on-flight and low continuation cost in order to endure at the decisive environment. In this article proposed a unique AUV, called Unmanned Aquatic Vehicle (UAV) inspired by the approach of flying fish, this can able to maneuver in underwater with high competence, in which estimation of resourceful have been derived based on theoretical design, manipulation realization process, communication, a existence of a UAV. Advanced numerical imitation have the ability to solve decisive problem so in this paper used CFD, in which, the ordered grid of the computational models for dissimilar types of UAVs is generated by Ansys ICEM CFD 16.2. This discretized model represents as the imitation of UAV, which is used to forecast the flow performance of the orientation module, and examine the hydrodynamic belongings on its sub-components. In this article, ANSYS-FLUENT 16.2 software is used as arithmetical solver tool, which is a influential tool for solving troubles concerning fluid mechanics. Results of the velocity, pressure allocation, and drag coefficient are analyzed. The characteristics of the drag, lift, pitching moment partial by the distance to the sea underneath and the attack angle are studied, which provided the path for UAV intend optimization
