Design and Computational Analyses of Nature Inspired Unmanned Amphibious Vehicle for Deep Sea Mining

Abstract

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.

Nature-Inspired Design and Advanced Multi-Computational Investigations on the Mission Profile of a Highly Manoeuvrable Unmanned Amphibious Vehicle for Ravage Removals in Various Oceanic Environments

“…Here the wing designs from the tropic bird which is the double tabard wing and the location of the wing is high wing. A large size fixed wing is designed for high lift generation, so that the lift and buoyancy force overcomes the gravity force to make the UAV float [47,48]. The wingspan of the UAV is taken from an adult tropic bird wing.…”

“…The relationship between wingspan, chord length, and wing area for a constant-chord swept-forward wing is given in Equation ( 5) [13,16,23,47,[53][54][55][56][57].…”

“…From the tropic bird, the primary design details concerning the first taper ratio is obtained, which is the slightly tilted constant-chord swept-forward wing. The swept angle formula is given in Equation ( 6) [13,16,23,47,[53][54][55][56][57].…”

“…Since the next part of the overall wing is planned to impose tapered with backward swept, the conventional equations for such a wing configuration has been attained [13,16,23,47,[53][54][55][56][57]. Especially, Equation ( 7) contains an analytical description of the planform area of the ta-pered with backward swept (TBS) wing and Equation ( 8) contains the analytical description of the aspect ratio of the TBS wing.…”
