Abstract
Currently, unmanned aerial vehicles (UAV), are playing an active role in various situations. However, because of its size and other limitations, the commonly used UAVs (from now on, just called as drone) do not have the long endurance capabilities of large aircraft. Of course, long flight is not the original intention of its design, but flexibility is its main characteristic. This results in the need for frequent replacement and recharging of battery equipment. It may be easy to replace the batteries on land, but it will be more difficult to do the same offshore. Also, there is always the danger of drone falling into the water due to insufficient power. To overcome this problem, it is imagined to place a floating body such that the drone can be docked as and when necessary while flying over the water for maintenance and battery replacement.
Therefore, in this preliminary study, we aim to model the basic physical phenomena mainly on how the drone’s descent flow affects structures such as small floating bodies. The effects of drone descent flow on a small floating body and resulting load distribution was investigated both experimentally and numerically. Further, the mechanism of drone descent flow was examined in detail.
The drift simulation of the floating body due to the drone descent flow was performed with high accuracy, and the model of the drone’s descent flow became clear.
