Embodiment 1

[0036] like Figure 1A As shown, the transportation protection device of the large-scale spacecraft provided in this embodiment is soft, specifically, the protective layer structure is the armor clothing 1, and the armor clothing 1 is wrapped on the outside of the rocket body 2 of the rocket, and the armor clothing 1 is also A fastening device 6 is provided for fastening the armor clothing 1 on the shell of the rocket. Wherein, the armor clothing 1 in the present embodiment is made of the protective cloth woven from the above-mentioned ultra-high molecular weight polyethylene fibers.

[0037] like Figure 1B As shown, the protective layer structure in this embodiment includes the armor jacket 5 made of protective cloth, the armor jacket 5 is arranged as a plurality of splicing blocks, each splicing block forms a pocket-type sandwich structure, and is connected to form a protective layer structure. like Figure 1C As shown, each splicing block is provided with a protective p...

Embodiment 2

[0046] In this embodiment, the transportation protection device of the large spacecraft provided by this embodiment is hard, specifically, such as Figure 3A As mentioned above, the protective layer structure in this embodiment is the protective cover 7, and the protective cover 7 covers the outer side of the rocket body 2 of the rocket. like Figure 3BAs shown, the protective cover 7 in this embodiment includes a protective plate 8 and a steel frame 9, and the protective plate 8 is formed by pressing ultra-high molecular weight polyethylene fibers with a thickness of 5 mm. Among them, a group of protective plates 8 made into a specific shape that matches the shell of the rocket cooperates with the steel skeleton 9 to form a basic protective cover unit 10, and a plurality of suitable protective cover units 10 are set according to the length of the rocket body The connections make up the whole of the large shield. In addition, after the protective cover is installed as a larg...

Embodiment 3

[0049] In this embodiment, the transportation protection device of the large spacecraft provided by this embodiment is soft, specifically, such as Figure 4A As shown, the protective layer structure in this embodiment is a protective cover 11, and the protective cover 11 covers the outer side of the rocket body 2 of the rocket. like Figure 4B The protective cover 11 is composed of a protective cloth and a steel frame 9, and the steel frame 9 is set to a shape compatible with the shell of the rocket body. The protective cloth passes through the steel frame so that the inner diameter of the protective cover 11 is basically attached to the outer edge of the arrow body protrusion. Wherein, the protective cloth in the present embodiment is a 7mm thick UD composite cloth pressed by ultra-high molecular weight polyethylene fibers, and several protective cover units are connected to form a large protective cover.

[0050] Wherein, the UD composite cloth 12 in the protective cover 1...

Abstract

The invention provides a large spacecraft transportation protecting device. The large spacecraft transportation protecting device comprises a protecting layer structure; and the protecting layer structure is matched with an external structure of a spacecraft, and is used for wrapping whole or partial structure of the spacecraft, wherein the protecting layer structure adopts a material of ultrahigh molecular weight polyethylene fibers. The ultrahigh molecular weight polyethylene fibers are woven as protecting cloth to form the protecting layer structure; a protecting armor cover formed by the protecting cloth is matched with foam and a protecting plate to form a protecting armor; or the protecting plate woven by the ultrahigh molecular weight polyethylene fibers is matched with a steel skeleton to form a protecting cover; or the protecting cloth and the steel skeleton are matched to form a protecting sleeve. The protecting layer structure of the protecting device is set as the ultrahigh molecular weight polyethylene fibers, so that the types are various, the adaptability is high, and the transportation safety of the spacecraft without a railway insulation vehicle shell and a special packing container is guaranteed.

Description

technical field [0001] The invention relates to the technical field of transportation of large spacecraft, in particular to a transportation protection device for a large spacecraft during railway and road transportation of rockets. Background technique [0002] After the aerospace products are tested by the production unit, they are generally transported to the launch site by rail or road. For the launch vehicle and its cabin, use a special railway transport insulated vehicle (Ω vehicle) for railway transportation; use a flatbed vehicle for road transportation, and place the product directly with a rainproof tarpaulin or use a special packing box. The disadvantages of the above transport devices are: [0003] 1. It is necessary to design and produce special railway insulated cars and special product packaging boxes. The cost of a single piece of small batch is relatively high, and the versatility is not good; [0004] 2. Due to the limitation of the railway transportation...
