specific Embodiment approach 1

[0015] Specific implementation mode 1: In this implementation mode, reactive glue is used to realize the docking between tiny spacecraft, such as Figure 2-4 As shown, the specific steps are as follows:

[0016] 1. Coat the surface of the flexible unfolding device with reaction glue, the reaction glue adopts two-component adhesive, and seal the two components into the microreactor respectively (the microreactor is spherical, its size is 2-200 μm, and the capsule The wall thickness is 10-20 μm), the two components are separated and no reaction occurs.

[0017] 2. The above-mentioned flexible deployment device is sealed and stored in the launch cabin of the spacecraft in a folded form ( figure 2 ), after entering the predetermined track, open the airtight device, and stretch out the folded flexible deployment device ( image 3 ), exposed to vacuum, the microreactor ruptures, the two components of the two-component adhesive mix, and the curing reaction occurs rapidly, achievin...

specific Embodiment approach 2

[0024] Embodiment 2: This embodiment is different from Embodiment 1 in that, considering the reaction speed of different adhesives, reactive adhesives and pressure-sensitive adhesives can be used in combination.

[0025] Coating the above two adhesives on the surface of the flexible deployment device to obtain a reactive docking device, the reactive adhesive and the pressure-sensitive adhesive are sealed in the microreactor, and the pressure-sensitive adhesive will quickly Realize bonding, and play the role of fixing the docking of two spacecraft; after a certain period of time (such as 1-60 minutes), the reactive adhesive can achieve firm bonding, so that after the two spacecraft are docked, there will be a firm of bond strength.

[0026] The pressure-sensitive adhesive can be selected such as acrylate pressure-sensitive adhesive, silicone and other resin-type pressure-sensitive adhesive, natural rubber pressure-sensitive adhesive and the like.

specific Embodiment approach 3

[0027] Specific embodiment 3: The difference between this embodiment and specific embodiments 1 and 2 is that the reactive docking device is folded and stored airtightly in two spacecraft launch cabins that need to be docked at the same time during launch ( Figure 5 ).

Abstract

A spacecraft space firm docking method relates to tiny spacecraft space docking methods. According to the spacecraft space firm docking method, a microreactor coated with reactive adhesive is coated on the surface of a flexible unfolding device; the flexible unfolding device is folded and stored in a spacecraft launching cabin in an enclosed mode during when the spacecraft launching cabin is launched; when the spacecraft launching cabin is in a pre-selected orbit, the enclosed device is opened to enable the flexible unfolding device to extend out and be unfolded slowly; when the flexible unfolding device touches another spacecraft, a permanent firm bond is achieved through the reactive adhesive released by the broken microreactor. The spacecraft space firm docking method utilizes the flexible slow unfolding device to buffer the flight speed and the docking force, and utilizes the reactive adhesive which reacts in the orbit in the space to bond the two spacecrafts firmly as a whole to further achieve permanent docking of the two spacecrafts in the space, so that the flexibility, the reliability and the success rate of spacecraft docking can be improved and the difficulty of the docking mode is reduced.

Description

technical field [0001] The invention relates to a space docking method of a tiny spacecraft. Background technique [0002] Space rendezvous and docking is an extremely complex space operation performed by two or more spacecraft in space. Space rendezvous and docking is a very complex and difficult technology in the current world aerospace field, and various spaceflight countries are constantly investing a lot of manpower, material and financial resources in active exploration and research. [0003] At present, the main docking method is mechanical docking. Through the coordination of orbital parameters, two or more spacecraft can reach the same position in space at the same time, and then connect them as a whole through a special docking mechanism. However, the two spacecraft must reach the same position in space at the same time under high-speed flight, and there is a risk of collision if they make mistakes. Therefore, space rendezvous and docking is a very complex and di...
