Title:
UNMANNED AERIAL VEHICLE SURFACE COATING, PREPARATION METHOD THEREFOR, AND UNMANNED AERIAL VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/066030
Kind Code:
A1
Abstract:
The present application provides an unmanned aerial vehicle (UAV) surface coating, a preparation method therefor, and a UAV. The coating at least comprises: an adhesive layer, an anti-oxidation layer, an oxygen barrier transmission layer, and a heat insulation and cooling layer. The coating is fabricated on the surface of a UAV body or covered on the surface of the UAV body by means of a composite material matrix. The UAV body is made of a lightweight material. The composite material matrix comprises a resin-based composite material matrix and a ceramic-based composite material matrix. The thickness of the adhesive layer is 20-200 μm, the thickness of the oxygen barrier transmission layer is 20-100 μm, and the thickness of the heat insulation and cooling layer is 80-1000 μm. In the present application, by combining the extremely low thermal conductivity, high reflectivity and strong oxygen barrier transmission of each layer of material in the coating, the UAV body has oxidation resistance, the working temperature of the UAV is improved, and it is ensured that the UAV may be used in fire rescue and may be used for long-term service.
