Skin, bulkhead integrated unmanned aerial vehicle body and manufacturing method of bulkhead integrated unmanned aerial vehicle body

Abstract

The invention relates to the technical field of unmanned aerial vehicles and provides a skin, a bulkhead integrated unmanned aerial vehicle body and a manufacturing method of the bulkhead integrated unmanned aerial vehicle body. The skin is of a sandwich structure, a middle layer of the skin is made of cork wood, and an upper layer and a lower layer are carbon fiber woven cloth. The skin is obtained in a laying manner and every two adjacent layers are bonded through epoxy resin glue. A bulkhead is arranged in the skin to form the bulkhead integrated unmanned aerial vehicle body. The bulkhead is made of the cork wood. The weight of the unmanned aerial vehicle body can be reduced, the structural strength of the unmanned aerial vehicle body can be improved, and the manufacturing cost of the unmanned aerial vehicle body can be reduced. The invention further provides the manufacturing method of the bulkhead integrated unmanned aerial vehicle body.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an integrated unmanned aerial vehicle fuselage with a skin and a frame and a preparation 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. [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 ba...

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.
