Abstract
During night flights of unmanned aerial vehicles, determining the location of the device during take-off and landing and the possibility of injury to maintenance personnel from a rotating propeller poses a certain problem. The problem is especially pronounced with a large diameter of rotor blade, which is difficult to highlight with a strobe light. The article describes the design of the rotor blade tip’s illumination system, which can be placed on propellers of any diameter without an additional battery source. This allows not only to make these lighting systems maintenance-free but also to fly in extreme conditions of low temperatures. This novelty will be especially useful when operating in the Arctic, where the polar night lasts for several months and there are very low ambient temperatures.
