- Unmanned Amphibious Vehicle (UAV) is an integrative working environments based vehicle, which doesn’t allocate the place for onboard pilots. Mostly, unmanned amphibians have been controlled through pre-provided algorithms in the predestined paths. Aerodynamic and hydrodynamic working conditions are the compositions of aforesaid integrative environments, wherein the possible lifespan affecting failure of UAV may chance to happen in a high manner. Thus, the multidisciplinary investigation on UAV and it's every component needs to be done in order to pick the suitable UAV parts for both missions executing conditions. This work deals the comprehensive computational investigations on a different number of blades equipped propellers for the proposed cum nature-inspired UAV under aerodynamic and hydrodynamic loading conditions. Three different propellers are uniquely constructed based on the aerodynamic environment reference with the guidance of analytical formulae and thereafter modeling processes are executed through CATIA, which is an advanced modeling tool. Transient analysis-based rotodynamic computations are completed on all the propellers under different RPMs, then dynamic forces in and around the propellers are tabulated for parametric investigation. Based on the high propulsive efficiency, the suitable propeller is shortlisted for both working environments. The shortlisted propeller is incorporated with the UAV, which is completely ready for deployment. The working deployment behaviors are analyzed through ANSYS Workbench 17.2 on the entire updated UAV. Finally, the suitable UAV and its components are picked for the complicated applications. The targeted application of this UAV is to provide surveillance at international’s maritime borders. Especially the UAV is indented to detect the intruders’ presence at aforesaid borders.
