“…The aerodynamic flow velocity of 10 m/s based computational results is shown in Figures 10 to 12. In Figure 10, the negative sign of pressure is corresponds for dynamic pressure and the velocity induced by the shape of the UAV is 2.414 m/s [Vijayanandh R et al (2020) and Vijayakumar Mathaiyan et al ( 2011 FR4 based composite is reacted lower than other lightweight materials under aerodynamic load. Thus, the lifetime of this same GFRP composite is quite higher than other lightweight material.…”

Nowadays Unmanned Amphibious Vehicles [UAVs] are employed in many applications such as oceanic research, deep sea exploration, mapping, naval surveillance, and disaster monitoring and fisheries protection. The use of UAVs in military and other applications has steadily increased over the few years. On the other hand, there has been a tremendous increase in ocean exploitation. Though technologies are increasing incrementally, nature is exploited adversely. Advancement in ocean transportation, shipping, sewage wastes filled the ocean with tonnes and tonnes of debris and oil wastes. This ravage fills affect the complete marine ecosystem. This in turn makes the ocean toxic. Advancements have been made in recent years to clean up the oil spills. The noted projects such as Sea bin, super high-tech sponges etc. All these innovations are the static one which cannot move along the waves of the ocean. The static form of these inventions could not be used to clean to the larger extent. Therefore, this study aims to build an UAV which is a movable one, can detect the debris and clean those by incorporating existing cleaning techniques. Since the UAV has to sub merge under the water to some extent, it should be designed in such a way by considering both the hydro-dynamical and hydro structural aspects of it. The unique point in the paper covers the flexible cum efficient design of the UAV. The design of the tropical bird is chosen for the efficient model of the UAV. With the few known parameters of this species, the UAV has been designed to achieve the maximum efficiency. The tropical bird chosen has the higher rate of climb, which is the desired requirement for this study. The propeller is uniquely designed based on aerodynamic cum hydrodynamic data so as to balance both the effects. With the design data estimated using analytical formulae, the UAV has been constructed. Following the design, the complete analyses on aerodynamic, aero-structural, hydrodynamic and hydro structural computations are completed. Finally, the employment techniques such as ravage removal mechanism, integrated rotor for the selected application will be integrated. CATIA and ANSYS Workbench are the major tools involved in these comparative investigations, in which modelling of UAV is computed in CATIA and fluid pressure, structural deformations, stresses on UAV are computed through ANSYS Workbench.

“…After a method was developed for constructing this UAmV, the next major phase comprised domain preparation, discretization, and computational procedure. These phases are based on data from the third literature survey [16][17][18][19][20][21][22]. Since the authors of this current work have predominantly relied on the ANSYS Workbench tool for all kinds of computations, this third sub-section is filtered and focused only on obtaining the boundary and initial conditions relevant for the aforesaid computational set-up.…”

The information about the development of control volume, procedures to develop structural meshes, and procedures to attain reliable outcomes for computational hydrodynamic simulations were obtained [16][17][18][19][20][21][22]. Apart from the primary conditions, the secondary conditions provide significant support in computational fluid dynamic (CFD) simulations.…”

“…From Table 1, it was found that symmetrical characteristics-based NACA aerofoils were used in all kinds of UAmVs. Based on the literature surveys, the authors developed Minerals 2022, 12, 342 6 of 43 four research articles [14,[20][21][22] that demonstrate the major constraints on the development of symmetrical NACA aerofoils-based UAmVs, wherein the required lifts were achieved in all the cases for the maximum speed of 15 m/s at various angles of attack. Technically, the flow in and over this current UAmV is mostly laminar, so the implementation of low Reynolds Number-based aerofoils in this work has been suggested.…”

This paper presents the design calculations, implementations, and multi-engineering based computational constructions of an unmanned amphibious vehicle (UAmV) which efficiently travels underwater to detect and collect deep-sea minerals for investigations, as well as creative usage purposes. The UAmV is expected to operate at a 300 m depth from the water surface. The UAmV is deployed above the water surface near to the approximate target location and swims underwater, checking the presence of various mining, then extracts them using a unique mechanism and stores them in an inimitable fuselage location. Since this proposed UAmV survives in deep-sea regions, the design construction of this UAmV is inspired by hydrodynamic efficient design-based fish, i.e., Rhinaancylostoma. Additionally, standard analytical approaches are followed and, subsequently, the inimitable components such as wing, stabilizers, propellers, and mining storage focused fuselage are calculated. The computational analyses such as hydrodynamic investigations and vibrational investigations were carried out with the help of ANSYS Workbench. The hydrodynamic pressures at various deployment regions were estimated and thereafter the vibrational outcomes of UAmVs were captured for various lightweight materials. The computed outcomes were imposed in the analytical approach and thereby the electrical energy generations by the UAmV’s components were calculated. Finally, the hydrodynamic efficient design and best material were picked, which provided a path to further works on the execution of the focused mission. Based on the low drag generating design profile and high electrical energy induction factors, the optimizations were executed on this work, and thus the needful, as well as suitable UAmV, was finalized for targeted real-time applications.
