Method and shell structure for reducing an electromagnetic footprint of an unmanned aerial vehicle

Abstract

The present patent disclosure concerns a method of reducing an electromagnetic signature, such as a Radar Cross Section (RCS), of an unmanned aerial vehicle, UAV, comprising a frame having a central body and two or more outer body sections extending from the central body, the method comprising: providing a composite material comprising a polymer matrix and a graphene-based material, wherein the graphene-based material is dispersed within the polymer matrix, wherein the composite material comprises 1 to 20 wt% of the graphene-based material per weight of the composite material; forming at least one shell structure made of the composite material, wherein the at least one shell structure is configured to cover at least a part of the UAV when the UAV is in flight; and mounting the at least one shell structure onto the UAV Further disclosed are a kit of parts comprising the UAV and the at least one shell structure, the shell structure, a composite material, and a method of manufacturing of the shell structure.
