Fixed-wing unmanned aerial vehicle body and manufacturing method thereof

Abstract

The invention provides a fixed-wing UAV body and a manufacturing method thereof. The UAV body includes a fuselage and a wing set, and the wing set includes a main wing and an empennage arranged on both sides of the fuselage. A wingtip is respectively arranged on both sides of the wing; the materials of the fuselage and the wing group are in a layered structure; cloth and the second carbon fiber cloth; the materials of the main wing and the wingtip respectively include the first glass fiber cloth, the second glass fiber cloth, the first polyvinyl chloride cloth and the third glass fiber cloth which are sequentially connected in layers; the The material of the empennage includes a first glass fiber cloth, a second glass fiber cloth, a first polyvinyl chloride cloth and a third glass fiber cloth which are sequentially connected in layers. The materials used for the fuselage and wings of the drone are light, and the tensile strength and tear resistance of the fuselage and wing materials are improved, which can ensure the structural strength of the drone.

Description

technical field [0001] The invention belongs to the technical field of unmanned aerial vehicles, and in particular relates to a fixed-wing unmanned aerial vehicle body and a manufacturing method thereof. Background technique [0002] At present, with the development of informatization, UAVs are widely used in the fields of earthquake relief, small-scale battlefield reconnaissance, and strike effect evaluation. Light weight, miniaturization, long endurance and high safety are the distinctive features and technological development directions of UAVs that distinguish them from manned ones. [0003] Most of the existing drones are made of polystyrene foam or balsa wood skin plus FRP. If polystyrene foam is used, the polystyrene foam needs to be cut in the process of forming the curved surface of the fuselage. Faced with high requirements and time-consuming cutting process, the preparation cost of the UAV body is increased. At the same time, the foam is easily corroded by glue, ...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing drones are made of polystyrene foam or balsa wood skin plus FRP. If polystyrene foam is used, the polystyrene foam needs to be cut in the process of forming the curved surface of the fuselage. Faced with high requirements and time-consuming cutting process, the preparation cost of the UAV body is increased. At the same time, the foam is easily corroded by glue, and after forming, it is easy to absorb water and get damp, resulting in deformation of the shape and reducing the strength of the UAV structure; If it is made of balsa wood skin and FRP, the material is relatively thick, resulting in excessive weight of the body after molding, which seriously reduces the load capacity of the drone, and the parts are relatively fragile in low temperature environments and are easily damaged during use.
