Abstract

The invention relates to the technical field of unmanned aerial vehicles, in particular to skin which is of a sandwich structure. The upper layer and the lower layer of the skin are both made of carbon fiber woven fabric, and the middle layer of the skin is made of polymethacrylimide foams. The skin is achieved in a laying-up mode, and two adjacent layers of the skin are bonded through epoxy resin glue. On the basis of the skin, the invention further correspondingly provides an unmanned aerial vehicle wing, a manufacturing method of the unmanned aerial vehicle wing, an empennage and a manufacturing method of the empennage. Accordingly, the weight of the unmanned aerial vehicle wing and the empennage can be lowered, the structural strength of the unmanned aerial vehicle wing and the empennage can be improved, and the manufacturing cost can be lowered.

Description

technical field

[0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a skin, an unmanned aerial vehicle wing and a preparation method, an empennage and a preparation method. 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, it is necessary to cut the polystyrene foam during the molding process of the wing or empennage, which is complicated. The curved surface has high requirements on the cutting process and takes a long time, which increases the preparation cost. 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, which reduces the strength of the dron...

Examples

Embodiment Construction

[0051] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0052] like figure 1 Said, the invention provides a skin, the skin is a sandwich structure, the upper and lower layers are carbon fiber woven cloth M, the middle layer is polymethacrylimide foam N;

[0053] The skin is realized by laying layers, and two adjacent layers are bonded by epoxy resin glue.

[0054] Preferably, the epoxy resin glue is formed by mixing and stirring epoxy resin and curing agent in a mass ratio of 100:8.

[0055] Correspondingly, such as figure 2 As shown, the present invention provides a kind of unmanned aerial vehicle wing, and described unmanned aerial vehicle wing comprises wing spar 1, rib 2 and wing skin 3;

[0056] The wing skin 3 forms the configuration of the wing, and the wing spar 1 and the rib 2 are placed inside the wing;

[0057] The wing spar 1 and the wing skin...
